Crafted from premium 18/8 stainless steel with dual-wall vacuum insulation, this versatile, lead-free beverage container maintains optimal drinking temperatures up to six times longer. Its innovative 3-in-1 design seamlessly transitions between an insulated tumbler, 12 oz can cooler, and 12 oz bottle cooler. Included are two functional attachments: a clear, screw-on sip-through lid and a black twist-top rubberized ring that securely holds standard cans or bottles. Thoughtfully engineered to fit most corporate and personal coffee machines, it combines form, function, and adaptability in one sleek solution.
