What Does Alimasy’s Lifetime Warranty Cover?

For your peace of mind, all Alimasy products come with a lifetime warranty against defects in materials or workmanship*.

The lifetime warranty only applies to the original owner of an Alimasy product which has been used under for the purpose intended in a responsible and normal manner.

The lifetime warranty does not cover products subjected to improper use, cosmetic changes, bought second hand or not purchased directly from Alimasy, or without proof of purchase. This warranty does not apply to damage caused through typical wear and tear, unreasonable use or neglect.

*Zippers: Yes, our Japanese YKK zippers are covered by our warranty for 2 years from purchase. Japanese YKK zippers are the most expensive and considered to be the most reliable zippers available. With normal use Japanese YKK zippers will consistently perform really well for years.

We do understand though that manufacturing defects can rarely occur with any component of a product including the best zippers in the world! 

As such, zipper issues will only considered to be manufacturing defects for the first 2 years after purchase. After two years of purchase zipper issues are considered to be normal wear and tear. The reason for the distinction for zippers is that we have found that because of the nature of zippers and their prominent use on our products, any and all manufacturing defects on zippers will come to light very quickly after first use of the product, or within the first 2 years of use.

To ensure the backpack stays in top shape for as long as possible, we’ve put together some easy-to-follow care instructions. These tips will help you keep the backpack looking great, feeling comfortable, and lasting longer.

Everyday Use

  1. Avoid Overloading: Pack only what they need for the day. This not only makes the backpack lighter and more comfortable to carry but also prevents unnecessary strain on the zippers and seams.
  2. Balanced Packing: Distribute the weight evenly by placing heavier items, like books, closest to the back and lighter items towards the front. This helps maintain the backpack’s shape and keeps it balanced.
  3. Use All Compartments: Make use of all the pockets and compartments to keep items organised and prevent any one section from becoming too bulky.
  4. Handle with Care: Use the top handle to lift the backpack rather than grabbing it by the straps, which can cause wear and tear over time. Avoid dragging the backpack on the ground to prevent scuffs and damage.

Storing the Backpack

  1. Dry and Cool Place: When the backpack is not in use, store it in a dry, cool place. Avoid damp areas to prevent mould and mildew and avoid prolonged exposure to direct sunlight to prevent fading.
  2. Empty the Contents: Regularly empty the backpack to remove any forgotten food items, papers, or other belongings. This not only keeps the backpack clean but also lightens the load for the next use.
  3. Hang it Up: Use a hook or peg to hang the backpack by its top handle instead of lying it flat when not in use. This helps maintain its shape and makes it easy to grab and go.

Loading the Backpack

  1. Smart Packing: Place heavier items at the bottom and lighter items on top. This keeps the centre of gravity low and makes carrying the backpack easier.
  2. Protect Fragile Items: Use the padded sleeves or sections for fragile items like tablets or laptops, and keep them secure to avoid damage.
  3. Secure Loose Straps: Tuck in or secure any loose straps to prevent them from getting caught or causing trips.

Cleaning the Backpack

  1. Spot Clean with Care: Use a damp cloth, mild detergent, and a soft brush to gently scrub away any dirt or stains. Avoid soaking the backpack or using harsh chemicals.
  2. Rinse and Dry: After spot cleaning, rinse the area with a cloth dampened with clean water to remove any soap residue. Pat dry with a towel and then air dry completely in a well-ventilated area, away from direct sunlight.
  3. Regular Maintenance: Give the zippers a quick brush to remove any dust or dirt. If they start to stick, a little lubricant like candle wax or a specialised zipper lubricant can help them glide smoothly again. Turn the backpack inside out and use a vacuum with brush attachment to remove crumbs and dust.
  4. Removing Odours: For any lingering odours, place a small sachet of baking soda inside the backpack overnight to absorb smells.

By following these simple care tips, your backpack will stay in great condition and will be ready to tackle each day with ease. Should you have any questions or need further assistance, feel free to reach out to us.

Great quality

I ordered two medium sized backpacks for my twin preschoolers and they have been fantastic so far!! The zips are smooth and easy(so the preschoolers can pack/unpack their bags 👌🏼), the pockets are a good size and the patterns are adorable! Great colours and good quality fabric. Definitely recommend!

'Lego' kids midsized back pack

Love everything about this bag except the small front pocket with a horizontal zip. It has a loose inner pocket and when the bag is packed and you're trying to get something out of the small front pocket everything comes out with it lol. having the zip at the top would make it 5 stars!! Otherwise we love it! You can fit a hell of a lot in there!!!!

Best backpacks ever…

We love these backpacks. My kids love the prints (we got Lego and shark print) and how comfy the bags are to wear. They are super hard wearing and durable, I know they will last for years. Will definitely buy again in a bigger size when the boys go to high school.

Gorgeous 😍

My 8yera old daughter was very happy when see saw the bag she chose for school. The print is GORGEOUS and th materiel is very high quality. Glad I found this wonderful company. Will only get bags from Alimasy. Thank you!

A little small

I got this bag for my Prep girl who is 106cm tall. This is a good bag and she loves the colours and Rainbows. While I think this bag is a good size for Kindy or daycare,I should have gotten the large bag. It would be much better if it has the laptop slip in the second part like the larger bag has in the third part.
I find that space to be good for spare clothes, which I found my first child needed while in Prep and grade one.
This bag has only been used for 4 days (flooded at home in NQ) but so far it fits her need of lunch box, water bottle and change of clothes

Beautifully made with lovely bright but sturdy materials. Hoping this bag will last her through her primary and intermediate schooling journey.

Beautiful bag

We love our dinosaurs mid size backpack, the colours are great, it’s beautiful and gets comments everywhere we go. Perfect size for my 3yo to carry and fits everything he needs for daycare,
It would be even greater if there was maybe an internal pocket or divider to separate smaller items within the bag and if the pocket on the front was a bit deeper. But that’s just me being picky, we love it!

A
Anneke Mace (Waikanae, NZ)
Our favourite backpack

I bought it for my daughter who is starting school soon and she absolutely loves it. She’s been finding every excuse to pack her bag and take it wherever we gol. some features we love are the two elasticised pockets so she can carry her little sister’s drink bottle too. An extra hidden front pocket for treasures. Super comfy padded back and straps including the carry handle, as well as an extra handle for her bag hook (she was VERY excited by that!), special internal label to write her name.. The compartments are nice and roomy but the bag is a good size- not so big that she could climb in there herself. It feels very sturdy and good quality like it will last for years. We love the print too, lots of detail and very cute drawings. I’m going to have to get myself one!

T
Tessa Beaver (Auckland, NZ)
Love it!

The pattern/ design on it is super cute, the construction quality is fab and the weight distribution etc makes it the perfect size for my 2 year old to carry for daycare. We love it!

Fantastic quality

This was my first ever buy from Alimasy for my kindy going first born. I think its a good incestment. Looking at the quality im sure it will last a good couple of years.

Perfect for kinder

Our little one loves her backpack and has practiced with it every morning since arrival! Perfect size for a 3 year old to manage and fit everything in. Fabulous quality and design, thank you for a great product

Ashleigh Wood (Melbourne, AU)
Happy, but could be improved!

I'm happy with the quality. I bought the toddler size construction backpack for my 18mo who goes to family and regular daycare. I just wish it had pockets on the inside, for putting things in set compartments. In my son's old backpack it was more a nappy bag but had compartments inside, one had a zip and I'd put socks or shoes, the others were either side, like where you store a bottle on the outside and I'd put his bottles for milk in there or his hat/beanie. I also wish the front pocket was your normal backpack style that took up the bottom half so it could carry more things in it. The pocket this one has at the very front opens from the side and is very flat, I don't really put anything in it because it's so small. If you modified the front to be like a normal backpack, i could use the second section for dirty clothes, but instead I've strapped a small "makeup bag" to the back of my backpack from designer bums that I have the educators put dirty clothes in to keep things separate.
Some sort of "tag" or "hook" inside each compartment would be good too, to clip on holders for things like dummies. Every company does their own thing though, I'm just giving my personal opinion. I really love that this bag is big enough to fit his spare clothes plus a large lunch bag that fits a large bbox lunch box and snack box all in the back section! You guys should make swimsuits or hats in the patterns you use as they're so vibrant and fun :) I would buy my boy making items in the construction pattern.

Kaylah Mitchell (Brisbane, AU)
I have found it!

Best bag ever! I have finally found it.. the perfect size bag.. that is not only so pretty and stylish but tough too! thank you!

A
Amanda Ormesher (Perth, AU)
My Dino boys loves his kindy bag!

This is our second bag from you, such a great size the last is still going strong after over a year of everyday use.
One downside this bag does not have the internal zip pocket in the back section that we use for membership cards etc.
still a great backpack.

Transport Midsize Kids Backpack

Backpack is the perfect size for my boy heading into Kindy this year. The colours and transport print is very eye catching and he loves the designs! Couldn’t be happier with the product. This is the third backpack I’ve purchased from Alimasy.

B
Beth Miller (Sydney, AU)
Super happy kiddo

Kiddo is very happy with his bag, all ready for primary school. Bag is excellent quality, well padded, zippers feel very secure and size is perfect for a nearly 6 year old. Highly recommended. Next is to pick one for me!

R
Renee Ozorio (Tully, AU)
Monster Truck Midsize

Love the quality and feel. Zips are super easy to use. Purchased as a Prep bag, so we haven't used it yet but am interested to see how many years we can get out of it.

S
Samantha Foster (Adelaide, AU)
Love it!

Perfect size for kindergartener - small enough lengthwise that it fits comfortably on her back (she is a shorter 4 year old), but expands widely enough to fit everything that is needed, including ice pack lunchbag and winter spare clothes. Smooth zip which she can manage herself. Very happy!
