The richly textured leatherette sleeve is laser engraved with the Life Member logo and is water resistant and easy to clean. Features a clear lid and narrower bottom to fit most standard cup holders. Not recommended for dishwashers, hand wash only. Made from 18/8 gauge 304 food-grade stainless steel. The hole on lid is big enough for a straw.
