These food grade metal cups are extremely durable, making them ideal for families with young children. Unlike glass, they won't shatter if they are dropped on the ground. These cups are great to use in bar, restaurant and kitchen. Aluminum remains cool to the touch, helping the tumbler keep your beverage cold and refreshing. Enjoy juice, water, milk, soda, and more from this pack of tumblers. Your logo is welcomed to laser engraved or imprinting on the cups to show your brand.
