Great but slippery

Size: 3 Count

Always disliked how wash clothes are too gentle and soft. I don’t feel clean with them. This one however is very rough. Love it. I feel clean. I gave 4 stars b/c the cloth is very slippery. A bit hard to get a decent grip while using it. Literally slides right out of your hand.

Great washcloths

I’ve had mine for over 3 years now, and it still holds up perfectly! Worth every penny.

Nice, but too small...

Size: 3 Count

...for dudes with bigger hands. The softer black side is very soft, but basically worthless if you're wanting to really scrub dead skin away. The white rougher side is really nice and after scrubbing with it, you really feel clean. You can really feel your pores come alive when you're rinsing the suds away. I've only used the rough side. Now the disappointing part is that the cloth is just too damn small. Men with larger hands will have a hard time keeping the cloth in your hand - it's not big enough to drape over your hand so it scrunches up quite a bit when you're really trying to get a good scrub with it. If they made these in a larger size I would easily give it a "5".

Perfect wash cloth

Size: 3 Count

Perfect wash cloth, a soft side and an exfoliating side. Easy to clean I just throw it in with my towels.
