Designed to keep your wine refreshingly cool (and safe from accidental spills or curious flies), this sturdy tumbler pairs perfectly with poolside lounging, boat days, and picnics. Built with 18/8 kitchen-grade stainless steel, it's tough enough to handle any adventure and is rust - and puncture-resistant to keep up. Thanks to double-wall vacuum insulation, your wine stays chilled to perfection, while the dishwasher-safe MagSlider Lid provides extra spill protection and slides open with ease—because refills should be effortless! So, pour yourself a glass, take it anywhere, and toast to unbreakable moments.
