The Corkcircle PREMIUM STEMLESS 12oz Cup is crafted from stainless steel in a sleek, wine glass-esque profile. It features the brand’s proprietary triple insulation in a fully vacuum-sealed design, keeping your beverages cold for up to 9 hours. A silicone bottom ensures this steel glass doesn’t slip off slick table surfaces. The sliding, spill-resistant lid keeps your drinks’ cooler for longer. Lose the stem, keep it cold, and make every sip sparkle.
