Lock&Lock 3-Tier Airtight Bento Box

Three independent tiers with Lock&Lock's 4-hinge airtight sealing system. BPA-free polypropylene. Microwave-safe (lids removed), dishwasher-safe. Each compartment stays isolated during transport.
Lock&Lock 3-tier earns the leak-resistance slot through the same four-hinge mechanism that made Lock&Lock containers a global foodstorage standard. Each tier seals independently โ hinge locks on four sides create genuinely airtight compartmentalization between the rice tier, protein tier, and side dish tier. Inverted bag transport doesn't produce the soy-sauce-on-rice contamination that simpler clip-lid boxes allow. Three-tier stacking creates a tall profile that may not lie flat in some bags, and the box is heavy compared to the Japanese domestic options. Microwave-safe with lids removed; dishwasher-safe. Korean-made, widely available at major online retailers and in kitchen retailers.
