Great exfoliation
Color: yellow
This does a beautiful job exfoliating, no more flakey legs. And it's gentle enough for the rest of my body. I'm on my 2nd bar of soap in my 1st bag and it's holding up well. I give it a good rinse after each use and hang it on a hook in my shower to dry. Well worth the money.

Extremely satisfied with my purchase.
Color: yellow
The ‘bag’ size is big enough to fit a LARGE (up to a 10 ounce bar of homemade/ handcut soap) bar or many tiny pieces. I am tired of using body wash (full of harmful chemicals) & a ‘pouf’ that may not be getting fully clean after throwing it in the washing machine periodically. The fabric quality is organic, natural & PREMIUM! It has little loops on the fabric which are great for lightly exfoliating & cleaning the skin, has a bead to keep opening closed and the string is long enough to fit around your wrist to hold it easily while bathing or showering. As far as effectiveness, it gets very bubbly if you get the fabric wet 1st & then make some traction (rub the wet bag back & forth onto the wet soap bar) between soap and the bag. For washing, use ‘wash bags’ (which are sold on Amazon & other retailers in many sizes) to keep them from being torn from buttons, zippers, etc on other items in the wash. With 8 in a pack, you should always have a clean one to use, while washing a previously used one. Rinse it out & Hang it after use to fully dry.

I love these
These bags are the best for bar soap. They scrub and rinse out nice.

Great product
Color: yellow
These are great! Super lightweight, easy to wash, and not painful to scrub your skin with. The price is right and the product is durable, fits all kinds of shaped and sized soaps, lathers well, and does not carry an abnormal smell.

Highly recommend!
Color: yellow
Very pleased with this product. The bags are soft but still exfoliate well. They hold lather after wetting the outside, but then allow the soap to dry completely when hung by the drawstring. I will buy them again when I need them.
