Frequently asked questions

How is the large-format Square lunch box airtight?

The Square lunch box features intermediate lids with silicone seals and a valve to ensure an airtight closure. It allows you to carry your meals without any risk of leaks, even inside a bag.

Square vs Original bento: which should you choose based on your needs?

The Square lunch box offers larger compartments, ideal for big appetites, bulky mixed dishes, or for using only one compartment thanks to the two included elastic bands. The Original lunch box, on the other hand, allows for better food separation and is compatible with various accessories. The choice therefore depends on your eating habits!

Which accessories are compatible with the Made in France Square lunch box?

This large-format lunch box is compatible with the Pochette L, Fresh, and Arctic transport bags as well as the Temple M and L sauce containers. Slim Box cutlery can be placed diagonally under the top lid. To cut your bread, fruit, or cold cuts, you can also use the Cut Square cutting board, designed to fit between its compartments.

Under what conditions can the Square be used in the microwave and dishwasher?

This bento can be heated in the microwave for up to 3 minutes at 500 W, by lifting the valve and stirring the contents after 1 minute 30. For dishwasher use, place it on the top rack using a gentle cycle.

What is the warranty of the Square lunch box and what does it cover?

The lifetime warranty covers aesthetic defects identified upon receipt (scratches, printing defects), manufacturing defects (damaged valve or seal, warped container or lids), or assembly errors (a part color not matching the ordered product). However, it excludes damage caused by impacts, improper use, or normal wear and tear.

I was not very impressed with the quality of the bento box. The wooden container did not look streamlined as it has different wood color on each side, and the black container had slightly faded scuffs on its side likely as a result of the manufcacturing process. I expected a clear black matte color (and i have another monbento that is all onyx black so i know how they should look like). and i expect a streamlined wooden color not a container that clearly looks like it was made from different colors of wood. I paid a lot for this.
