xMeet the CS COSDDI 12 oz Vacuum Insulated Tumbler
This compact stainless steel cup is designed for everyday moments and on-the-go routines. Crafted from high-quality 304 stainless steel, its interior is taste-free and resistant to rust, while the lid uses food-grade silicone that is BPA-free. The result is a durable, dependable cup that feels premium in hand and travels well from home to office, student desk to city streets.
At the heart of this tumbler is a vacuum double-wall that minimizes heat transfer and helps maintain the temperature of beverages. The outer surface stays comfortable to touch whether your drink is steaming hot or refreshingly cold, while condensation stays where it belongs—inside the cup. The brown finish adds a warm, earthy aesthetic that fits a variety of styles and settings.
