The OMWKABS04-BK is a compact, lightweight, ABS plastic, internally sealed mouse that is washable and waterproof. It is resistant to dirt, debris, water, soap and other disinfectants. It is designed to withstand repeated cleanings in dusty, dirty, and damp environments that would otherwise ruin a regular mouse. This mouse is intended for use in hospitals, dental offices, laboratories, as well as food processing, manufacturing and industrial sites. It features a left and right click with a scroll wheel for convenient scrolling. The standard look and feel of this mouse makes it a perfect replacement for any mouse. This professional-grade sealed ABS plastic mouse can be cleaned with almost any antibacterial solution to prevent cross-contamination and the spread of germs (see WetKeys Cleaning Guide for list of recommended cleaning products).
