No plastic. No leaks. This rugged, long-lasting ECOlunchbox Bento Wet Box™ stainless steel food container is built to literally take a licking and keep on ticking without dripping.

Our Bento Wet Box container with its leak-proof lid features a soft-close latch and silicone gasket design by ECOlunchbox®.

With a big 40-oz capacity (1200 ml), this large rectangle bento box with lid is specifically designed to hold wet meals like saucy entrées, fluffy dressed salads, and generous take-out restaurant portions.

We have chosen not to use glue to attach the silicone gasket to the steel lid for ease of thorough cleaning. Glued gaskets accumulate food juice/junk and bacteria, so a removable gasket is the best food-safe design. The clear food-grade silicone gasket, which is tucked inside the perimeter of the lid, creates a leak-proof seal when the lunch box is clipped closed.
