When I open lunchbox the main component to put your food in, has not come down or open up like it needs to

This is a really cute lunchbox that my kids love, but it's impossible for them to close it back on their own.

[This review was collected as part of a promotion.] I like the bento box but the lid is not stable and broke easily.

[This review was collected as part of a promotion.] This bento box is so cool! I love the different compartments for different foods. The colors are so cute! And the added charms are adorable! The ice pack keeps food cool all day!

Works great, but for my 4 year old it is very hard to open and it s heavy.

Fortunately I ordered the green box but was delivered a pink box so will be returning
