The Kinsho Bento Box set uses a 3-compartment layout with a 2.2mm wall thickness, providing a sturdy feel for daily use. The chassis is made from high-density Polypropylene, which has a high melting point and is resistant to chemical leaching. The seal features an over-molded TPE layer designed to compress against the walls to keep food items in their respective places.
The latches are designed with reinforced pins for added durability. For best results, it is recommended to microwave only the main tray, as the seal on the lid can react to extreme heat differently than the plastic. The set is verified as FDA-compliant and is free from BPA and phthalates, ensuring a high standard of material safety for all family members.
For a lighter, 4-pack option with more compartments, consider the Lezuoey bento set. You can see more school and work-ready solutions in the insulated lunch bags category.
