Travel tumbler/Travel mug - double walled tempered glass cup with removeable infuser. Stainless steel, laser drilled infuser fits snugly into the silicone lid. Can be used with or without the infuser in place. Simply put your fruit or tea into the glass itself, then add hot/cold water, then carefully place lid with infuser onto the cup. The infuser will strain the fruit or tea as you drink the beverage. Double walled glass keeps drinks hot or cold. Plastic GOCLEAR label peels off easily without leaving any residue.
