The Pure Ceram coating on the inside and outside makes the cup resistant to acidic drinks, ensuring a neutral taste and preserving the natural aroma of the beverage. The ceramic coating provides an optimal drinking experience. The Tritan lid features a small opening for safe and comfortable drinking. The cup's insulating properties prevent condensation on cold drinks and keep the exterior cool to the touch when used with hot beverages. BPA-free, it's the perfect alternative to disposable cups, designed for years of use and reuse. Made of recyclable 18/8 stainless steel, both the cup and lid are dishwasher safe.
