SAFE & HEALTHY – Interior is made from high-quality 100% food-grade stainless steel, BPA-free, never rust, does not retain flavours or scents; The exterior and dividers are made from food-grade safe plastic, non-toxic and odourless; so you could use it with confidence.
• LEAK & SPILL PROOF – The lid of the lunch box has a heavy-duty silicone seal to prevent leak and spill, you could put the hot soup in the first layer; it is very tight to lock in freshness, leaks, and odours, but the silicone hole could be lifted up to release the pressure and make it easy to open.
