Brand new. Add a touch of enchantment to your hydration game. Features a glossy, light-catching opalescent finish that's out of this world. Crafted from stainless steel with proprietary triple insulation, this vacuum-sealed wonder cup just doesn’t quit. It keeps your beverages cold for 9+ hours and hot for 3. Stays cold even longer with drinks containing ice — even out in the sun. I have other Corkcicle items too • Slip-proof, silicone bottom • Easy-grip sides • Sliding, spill resistant lid
