🍱 THREE-PIECE LAYERED MEAL CONTAINER: Built to last from 100% rugged and tested stainless steel, this ECOlunchbox holds 4.5 cups (36 oz) food all together in three levels. Each level holds 1.5 cups (12 oz) and is clipped together. The stainless steel TriBento measures 4 inches high and 5.25 inches in diameter. The size fits a full meal and is idea for all types of foods so long as they are not too wet.
🚫 NOT LEAKPROOF: The container’s stainless steel lid is easy to use, even for young children. There are no gaskets in this lunchbox’s design, so it’s not appropriate for packing wet foods that might leak. If you’re looking for a leak-proof food container, check out other products by ECOlunchbox, such as our Blue Water Bento Splash Box and Blue Water Bento Seal Cup Trio that have silicone lids.
🌿 100% PLASTIC FREE, NON BREAKABLE & BPA-FREE: Made from the high-quality, food-safe stainless steel. Steel container is lighter than a comparable glass container and virtually non-breakable. ECOlunchbox stainless steel food containers, which are third party independently tested, are free of estrogen-mimicking toxins commonly found in plastic, such as BPA (bisphenol-A), BPS (bisphenol-S) and phthalates.
🍴 DISHWASHER SAFE: All parts of our stainless steel bento boxes are dishwasher safe, including the lid! No need to hand wash lids separately from the container bases like with other brands with lids made from plastic or with embedded gunky gaskets.
💡 TRUSTED MISSION-BASED BRAND: California eco mom and environmentalist Sandra Ann Harris designed the original ECOlunchbox stainless steel food container more than 10 years ago to pack lunches for her two young children. The woman-owned and led company continues as a mission-based, family-owned business dedicated to helping people reduce their dependence on plastics for health and environmental reasons. We stand behind our products and offer a one-year limited warranty against manufacturer’s defects.
