NATURAL & SUSTAINABLE MATERIALS- Winsa glass tumbler comes with a bamboo lid, 2 reusable straws, and a bonus straw cleaner. Features a food-grade silicone sleeve and non-slip base (BPA-free). Made of high borosilicate glass (odor/taste resistant).

ON-THE-GO CONVENIENCE- The bamboo lid is designed with a tight-seal silicone gasket for secure leakproof and spill-proof performance. With a 2.75-inch base, this glass coffee cup fits most car cup holders. Lightweight yet durable, ideal for the gym or commuting. The sweatproof and non-slip silicone sleeve comes in multiple color options for easy identification at home, work, or while traveling.

CRYSTAL CLEAR & PRISTINE TASTE - This perfectly sized 20oz glass tumbler beautifully showcases your beverages while ensuring pure, unaltered flavor. Unlike coated metal or plastic cups, our glass tumbler never retains residual tastes, guaranteeing your morning coffee tastes exactly as it should and your fruit-infused water remains refreshingly crisp.

CARE INSTRUCTIONS- The stylish drinking glass helps remind and motivate you to drink more water daily. The glass tumbler is dishwasher-safe, but the bamboo lid should be hand-washed and air-dried to ensure longevity.
