Plastic-free and leak-proof, the Seal Cup Trio is a three-piece set ideal for packing a variety of foods and keeping them separate. The containers are nesting, so you can pack up to a total of 5 cups of food in the morning and after you've eaten you can compactly tote them home by nesting each container inside the other. The non-toxic Seal Cup Trio makes your lunches greener and oceans cleaner by keeping dangerous plastics out of your lunch and out of nature.
