The Qwetch cups are designed to keep drinks hot or cold on the go. Each one is made from two layers of 18/8 (304) stainless steel which keeps the drink inside hot, but stays cool enough to carry.
The cup has a BPA free Tritan lid with stainless steel inside which means only stainless steel comes into contact with the drink inside the cup. The lid is not leakproof because it has a sipping opening. The cup will keep drinks hot for up to 3 hours or cold for up to 5 hours.
