Frequently Asked Questions
Are these lunch boxes truly leakproof?
Many of the bento-style Fimibuke models use silicone gaskets and individually sealed lids that are designed to be leakproof for sauces and moist foods; the Tiblue bag uses hot-welded seams and waterproof fabric to contain spills. Always test new containers at home with a filled liquid container before relying on them for a full day.
Which parts are dishwasher or microwave safe?
Most Fimibuke trays, removable jars, and utensils are top-rack dishwasher-safe (check under 80°C guidance) and the tray is microwave-safe in most variants. The lunch bag shells and some lids are wipe-only—refer to each product's instructions and avoid putting insulated shells in the dishwasher.
What size lunch box should I get for my child's age?
Preschoolers do well with compact bento boxes sized for small portions; elementary kids typically need 3–4 compartment bento boxes to cover a sandwich, fruit, and snack; older kids and teens often need a larger insulated bag that can hold multiple containers and a full water bottle. Consider daily appetite, after-school activities, and whether you pack hot meals when choosing capacity.
