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.
