  • Our take on the Seal Cup Trio

    The Seal Cup Trio is a three-piece nesting lunch container set made of type 304 stainless steel with silicone lids. The three cups hold 20, 12 and 7 oz, nest together, and weigh 9.6 oz as a set, so the whole kit is lighter than glass and won't break. Tare weights are etched on each base for delis and food bars that charge by weight. Unlike plastic containers, the steel and silicone are free of BPA, BPS and phthalates, and all parts are dishwasher and oven safe, though none are microwave safe. It suits people packing lunches, buying food by weight, or replacing plastic and glass containers.

    About the Seal Cup Trio

    The Seal Cup Trio is a three-piece nesting lunch container set. It is plastic-free and leak-proof, and it keeps different foods separate. The containers are type 304 stainless steel with non-toxic silicone lids.

    The containers nest inside one another, so the set packs down compactly after a meal. Together they hold up to 5 cups of food. The steel and silicone construction is lighter than glass and nonbreakable.

    The silicone lid and stainless container are free of estrogen-mimicking chemicals found in some plastics, such as BPA, BPS and phthalates. Tare weights are etched on the bottom of each container, so the set can be used at food bars and delis that charge by food weight.
