Our LunchSkins Reusable Sandwich Bags provide a green alternative to disposable sandwich! Each bag has a colorful and cheerful pattern to match your style. You can further personalize each bag by writing your name with a permanent marker on the nameplate. These bags are made from a thick cotton fabric that is coated with a food-safe polyurethane liner. This makes the bags grease-proof and moisture-proof, making them ideal for messy sandwiches and snacks. The fast-drying fabric means that these reusable bags are ready to go when you need them! Use them to carry more than snacks and sandwiches; these bags can also be used to hold lipsticks, dog treats, wallet and keys, ice, pacifiers, baby toiletries, cosmetics for when you travel, and any other treats or loose messy items. These bags are hand sewn in the USA and are dishwasher safe. In addition, they have been certified as lead, Bisphenol-A (BPA) and phthalate-free. The very thin layer of polyurethane has also been tested and found not to migrate into food or leave a "plastic" odor behind, thus meeting EU requirements for food contact. Velcro seal.
