Kensington ErgoSoft Wrist Rest for Mouse K52802JP Weight: 145g Body size: 15.5 x 7.5 x 1.5cm ErgoSoft wrist rest using a premium, soft, skin-like material unlike anything before. By combining TPU and gel cushion, it maximizes comfort during typing. The ergonomic design reduces stress and fatigue on the wrist. The soft surface material is resistant to sticking to the skin and easy to wipe clean, allowing for comfortable use even in the sweaty season. The rubber bottom is non-slip, allowing for secure fixation during use. I am selling this because I purchased a different item.
