Retro 51 Tornado rollerball, "Cat Rescue". If you love pets, this cute pen filled with cats will help rescue our furry friends. With each purchase of a Dog or Cat Rescue pen, Retro 51 will make a donation to Operation Kindness to help care for homeless dogs and cats until each is adopted into responsible homes forever. These brilliant colored Tornado Deluxe convertible rollers use a special capless roller refill that won't dry out if the tip is exposed. You can also convert it to a ball pen as well.
