Totally love this little lunch box I have made my sons lunch for 2 weeks now in it he loves the separate compartments, he loves that it comes with a little container for sauce or little snacks and that it comes with a fork and a spoon so we aren't always buying plastic forks and spoons.!

Over all great no complaints over here

Really Good quality

My 5 years likes his bento box. It is easy to open and carry it.  It is great for kindergarten student who goes to school half-day

Bento box

Sooooo I wanted to love this but it just doesn't work for me! For these to be useful your kids have to be the kind that eat everything!!! My kids don't and the leftovers have to be fished out or dumped in order to clean it. Also my kids couldn't get it securely closed on their own so food would be spilled out into the lunch box. Also the compartments are so small I just didn't love it. I felt like I was still using g additional containers. Will be giving them away. I did like the included utensils

Not for us, just ok, glad they were inexpensive

The compartments leak into one another. The lid also doesn't open all the way, maybe only to 90°. I bought two and one broke because the kids dropped it.

Moving On

I was really disappointed with this bento box. Despite being advertised as durable, it is not dishwasher safe. After just one wash, the plastic warped and now the lid no longer closes properly. This completely defeats the purpose of a bento box, as it no longer seals or functions as intended. I expected much better quality from this brand. I wouldn't recommend this product unless you plan to hand-wash it very carefully which if you are a busy parent, is not ideal.

Disappointing.

This is not a great bento style lunch box. Price and color were appealing, but the box leaks and the compartments are too small to allow for containers that might prevent this. Maybe we can use for crafts but not for lunch :(

Not a great bento style lunch box

Much cheaper than a Bentgo but way less sturdy. My hinges snapped after 2.5 months of use. The box itself doesn't nest super snug with the base.

Hinges are weak and snapped after 2.5 months.

In the listing, it says the item is food safe.  I read the label after receiving the item.  IT IS NOT FOOD SAFE and has a cancer warning on the back of the label.

NOT FOOD SAFE!
