Fantastic purchase completely happy
Color: Beige (4 Packs)
Awesome soap bag the construction is very sturdy and allows for good lathering and I would definitely purchase them again. It also helps with exfoliating so you’re getting two birds with one stone.

Great product for the price, would buy again!
Color: Beige (4 Packs)
Great bags. There is a ball to pull the top right but it slides back open so I just tied a knot in it but idk how I'll get it out to put more soap in. Otherwise a great product! Glad I bought them! Color is neutral, lather is good, very durable, easy to use, could be a little rougher (in my opinion) it's on the soft side, functions great besides top coming open, very durable!

Small to big soaps, not exfoliating
Color: Beige (4 Packs)
My soaps haven’t slipped out. I use dove bars and smaller round soap bars in them and I haven’t had any issues. They leave a room around my dove soap bars. I’m glad I can bar small to large soaps in this bag. I haven’t need to tie a knot on the end like I often need to do. They feel like a soft scrub on my body, not exfoliating. I enjoy my tan colors.

Not the best, but good enough
Color: Beige (4 Packs)
It is useful since it keeps the soap in and works well. The problem is that when the soap dries some parts of the bag become stiff and scratches your skin. It gave me a rash.
