Fantastic Box

This box is durable, easy to clean, and a great size for lunch or shareable snacks.

Favourite but sad no replacement parts

We loved this lunchbox! Super easy for my preschooler to open and he loved the pattern on top. However, when we lost the top snack box and reached out to purchase a replacement they weren’t able to which meant we had to get a whole new lunchbox and also means the other two sections are wasted as they aren’t used anymore.

Great lunchbox!

The tri bento works great to replace my old lunchbox. I love the compartments, the material, and the size (though it's a teeny bit smaller than I expected, it fits all my usual foods).

Big Snacks OR Full Meal

The Tri Bento in a circle shape holds a lot more food than I anticipated! With serving portions and a little room to spare, my elementary-age kids were full at lunch with a 3+ course meal. They also filled this up with snacks over the weekend just because they were so excited to use their new shiny metal Bento Box!
