Quick shipping, good seller
Style: Sustainable - Stretch Cloth, Size: 3 Count (Pack of 1)
These weren't what I hoped they were, so I wasn't all that pleased with them. The seller, though shipped them quickly. I cut them in half and am using them to scrub my back. I was looking for a cotton face cloth.

Gentle enough for everyday use
Style: Sustainable - Stretch Cloth, Size: 3 Count (Pack of 1)
These are my FAVORITE! I bought one at a local store and then couldn't find them anymore. Went online and finally found them on amazon! Gave one to my mom and boyfriend and they BOTH love it. It is gentle enough to use everyday.
