Plastic-free and leak-proof, the ECOlunchbox Seal Cup Trio (Set of 3) is a three-piece set ideal for packing a variety of foods and keeping them separate. The containers nest, 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. How nifty is that? Plus, the non-toxic Seal Cup Trio makes your lunches greener and our oceans cleaner by keeping dangerous plastics out of your lunch and our oceans.
