RT-SC01AM Antimicrobial Universal Keyboard Cap. This is a film-based keyboard protector designed for comfortable and easy to use protection for standard sized keyboards (full size with num pad, not for all ergonomic or multimedia keyboards). It can fit nearly any brand with the proper dimensions, it"s as easy to install as its inspiration: a shower cap. This design helps to keep out spills, dirt, crumbs, and other contaminants, and also makes cleaning the keyboard much easier. The Keyboard Cap is also very thin, transparent, and flexible, allowing you to type through it without any added resistance or inaccuracy. Also, unlike the normal Keyboard Cap, this comes with an extra silver-ion antimicrobial additive, which kills bacteria, algae, and fungi on the Cap. Perfect for hospitals, clinics, offices, homes, and more. Note: the Keyboard Cap is designed as a semi-disposable product: durable enough to last months of use, yet cost effective even if used as a one-time protector before it is sterilized or thrown away.
