These Wypall X60 reusable towels are the envy of all other paper towels. The blue towels are on a huge roll (you can get a holder for them), are perforated, and each is 12/5" X 13.4." And, they're reusable.The towels can be used for anything from solvents - they're great to have around when stripping a piece of furniture - to dirty greasy machine shop jobs, yard work, washing windows and just plain house cleaning. We tore off a half a dozen to keep in our cars. They're great for wiping down just about anything inside or outside a vehicle, dusting, washing or waxing. (Or changing the oil.)They aren't completely lint-free, but close enough for me. They're easy to rinse, dry quickly, and reuseable. They take a beating and stand up to it. Recommended whether it's for your home or shop or office.
