Review (5/5): If you like "scratchy" washcloths, just buy this. It's better, cleaner and just amazing.
I got 2 of these, 110 and 120 "grit" (for lack of a better word, and because these remind me of sandpaper).
The 120 is my favorite. It's better than any exfoliating brush, cloth or soap I have ever tried in my whole life. They were both VERY long, but I cut them in half and there was minimal unraveling (honestly, about 5 strings from the cut edges and it stopped. It's hard to even tell where they were cut now!). AND they rinse absolutely clean very easily. No having to squish them out multiple times like a sponge, and no having to hang them and wait forever for them to be dry (I live in GA, 70% humidity is normal here, so quick drying things are a huge plus for me).
