like they use at the barber shop.
in fact, if you just need a set of towels to use to clean your face after shaving, these would also be perfect for that as well. it's good to separate towels you use on your body from the ones you want to use on your face, so having a set dedicated for shaving is highly recommended.
look for barber shop towels that are made from 100% cotton, measure 15" by 25", and are machine washable and dryer safe.
for daily shaving, i recommend lab series power wash; it's one of the best face washes you can use before you shave, and great for all skin
