The Prologic Blackfire Twin Skin Carp Cup is a stainless steel mug built with a twin skin construction, which keeps drinks hotter for longer than a standard beverage container. Its anti-reflective Blackfire finish helps prevent stains from building up and makes the cup easy to clean. A custom camo wrapped handle provides a firm grip and a distinctive look, so you can return to a warm tea or coffee even after time away from the bank.
