MasterClass Eco-Snap sets a new standard for eco-savvy storage. You can refrigerate them, freeze them, microwave them and reuse them. And with their secure, snap-on lids, they're airtight and leak-proof, so they're perfect for long-term storage or quick packed lunches. How can one container do so much? With cutting-edge recycling technology, that's how. MasterClass Eco-Snap containers are made of Eastman Tritan copolyester, a revolutionary new plastic. It's formed from recycled plastic that's broken down into its chemical building blocks, then reassembled into a new polymer that's remarkably strong and as clear as glass. Use these airtight containers for food storage, meal prep, lunches on the go, and more. Then do it again, and again, thanks to their impressive strength and reliability. Explore the full Eco-Snap range to find stackable plastic food containers with lids in four useful sizes. All are dishwasher safe and BPA-free.
