A set of the matching Hybrood Roller Ball Pen & Etched Card Case with the "Hatch" design from designer and Karl Zahn. This pen and card case set is special in that it was designed to take advantage of the innate properties of brass and its remarkable ability to self sterilize. Within a few hours of contact with the brass ions, any bacteria or microorganism dies. This set comes in a tin designed to hold a bullet shaped pen and a card case. It comes with a black roller ball refill and is packaged in a black paper sleeve.
