Camco’s Wine Tumblers are a great addition to any campsite, tailgate or party! These ultra-durable tumblers are made with kitchen grade 18/8 stainless steel and the double walls vacuum insulate your beverage, keeping it hot or cold longer. The tumblers have a flat bottom, so they can be used with or without the colorful stems. The stems can be used to color code drinks, and help keep track of whose drink is whose! The lid is BPA-free and has a fully sealing gasket to help maintain beverage temperature and prevent spills.
