They measure approximately 7x7

These are 2ply ( 2 layers of flannel)
Made with 100% cotton  flannel. 
Serged edges. Can add frey check at the serging junction if you’d like just leave a note when you check out. I don’t use it on mine and have had zero issues but I know some buyers like them frey checked.
Just wash and reuse over and over. 
Depending on use and the amount you have, they can last for years! Most of mine are 6 years and still going strong!

CPSC compliant with stamped on care tags.

price is per wipe
