Red plus palm support is our extended palm support that provides even more comfort for your forearms while working. Made specifically for RollerMouse Red, Red plus palm support has all of the benefits of RollerMouse Red, with additional palm support. The extended wrist rest, made of the same leatherette as the standard wrist rest, adds an additional 2 inches (15.5 cm total) of support to your palms, wrists, elbows and forearms. Its tapered angle improves hand posture and pressure distribution. Red plus palm support promotes an even better and more ergonomic working posture for you, and additional comfort for computer users with larger hands and longer fingers.
