Liquid Anti-Friction Treatment LIQUID is designed for use with all types of hard surface mouse pads and mice, including optical and ball mice LIQUID is a water based, non-toxic, anti-friction treatment that has no wax or petroleum products in it. It is a silicon emulsion made with only top quality materials. LIQUID reduces `drag' by creating a micro fine anti friction layer between your mouse and surface, and helps protect your hardware from wearing out too quickly. LIQUID can help minimize hand fatigue in intensive applications due to reduced effort in mouse movement.
