The CleanBlockTM is a pen and stylus cleaner, designed to be a quick and easy solution to germ contamination and illness transfer. By sliding a pen in one hole of a CleanBlockTM and out the other, the 70% ethanol solution kills germs, fungi, and bacteria on the surface. The no-residue formula gives you a clean, dry writing utensil, ready for immediate use. The CleanBlockTM is designed to last for over 1400 uses, and is a simple, smart addition to any office, classroom, or healthcare facility. And, we’re proud to say that the CleanBlockTM is sourced, manufactured, and packaged in the United States of America!
