This Universal Iced Coffee Sleeve is a versatile 3-in-1 solution for iced drink lovers. Constructed from food-grade 18/8 stainless steel with double-wall vacuum insulation, it functions as a 28oz reusable travel tumbler and a sleeve that fits most small, medium, and large disposable takeaway cups. The insulated design keeps beverages cold for up to 12 hours and hot for up to 6 hours, minimizing ice melt and maintaining flavor. Designed for on-the-go use, the sleeve features a spill-resistant flip lid with a silicone ring, a stainless steel straw for dual drinking options, and a shape that fits most cup holders. The sweat-proof outer surface prevents condensation, while the thickened handle provides a secure, comfortable grip. It’s a practical choice for travel, work, fitness, and outdoor activities, and is presented as a reusable, everyday kitchenware option backed by a limited lifetime warranty.
