This is the second purchase for our second kid starting school. I can not fault it. It lasts longer than the school day and keeps everything perfectly cold. Great for their yoghurts and fruit. Lays flat under or ontop of the lunchbox in their lunchbag.
We love the design, customisation, layout and ease of cleaning. Kids are so thrilled and feel so cool at daycare/preschool with their special lunchboxes that they can easily open themselves.
This is my second purchase from Mum Made Yum, and I ordered two of these lunchboxes. My daughter is obsessed with the sparkles, and we decorated it ourself with stickers. She tells me every day at lunch time she smiles when she sees her box. Besides looking good, it is also actually leak proof and cleans very easily. Would so highly recommend!
My girls are so happy with their new lunchboxes. The quality is the best I’ve seen and I know they’ll be able to use these for years to come. Also, we weren’t expecting them to come so quickly which was a bonus!
Our 4 year old daughter was so excited to receive her ‘big school’ lunchbox for Christmas 😍 The design and quality is so sturdy and amazing! Delivery was quicker than expected, delivered beautifully wrapped and protected with care 😊 We then bought a second design after our first purchase as a back up, and our daughter loves them both as much as I do! Thank you ☺️🙏
This is so cute, my child really loves it. It’s also very practical, fits a lot of things and comes apart easily enough to wash (but stays in tact all day, even thrown in the backpack). Would highly recommend, such a fun and sturdy lunchbox
I’ve just ordered another one in the larger and smaller sizes
I love this so much. I just bought another one!
Fits even large lunchboxes, feels really sturdy at such an excellent price. Really cute design that my child loves
Absolutely love these lunch boxes, hence I have new ones for this year again. There was nothing wrong with last years ones, I just like getting new ones each year and my son will use last years ones for vacation care. Thank you so much amd wished I found them sooner
If you have a kid that loves everything about construction and you want to make them a fun lunchbox, then this sandwich cutter is perfect for you! My kid loved it! I love that is perfect size that cuts out the crust and so much bread is wasted like other cutters!
Brought this for our daughter to start prep in 2026. Easy to open for her and had plenty of space for me when packing her brain food. We got them personalised and it looks amazing.

The girls absolutely love their new lunch boxes! The purple sparkle is gorgeous, and the lunch boxes themselves are perfect as always. They can’t wait to use them next year! 💜
