In 2010, Rick Fredland discovered a huge void in the drinkware market. By using sustainable, safe, simple, durable, and versatile silicone material, he invented the perfect "glass." Risks were taken, creativity was encouraged, people came together, and a drinkware company specializing in silicone drinking cups (and later, straws, lids, and bowls) was born.This set of unbreakable wine glasses is the perfect silicone wine glass set to take with you wherever you go. They are the versatile, fun accessories that your indoor or outdoor bar has been missing. These tumblers are extra practical—never again will you have to worry about a broken wine glass or use those red plastic cups to hold your wine or cocktail. They are the perfect cups for your next picnic, tailgate party, or barbecue. These reusable, 14-ounce silicone beverage cups come in a wide variety of cool colors and are the fun way to chill by the pool or party on the beach.All Silipint products are made of sustainable, 100% food-grade, platinum-cured silicone.
