This Product keeps hot beverages at serving temperature on the go. It is coated with real cork, so that the high-quality plastic cup will remain cool to the touch, which is due to natural thermal insulation ability of cork. This anti-bacterial, eco-friendly cup includes a screw on lid with spill-proof silicone seal for leak resistance. The use of cork significantly reduces the use of plastic (makes it green). The isolation and anti-slip properties of cork make it the ideal coffee-to-go cup!
