Good for exfoliating
Color: Beige (4 Packs)
These are great for saving and using soap slivers. I can't stand to throw out something useful but once they get too small they're hard to hold onto. I had a mesh bag but it started to come apart and I thought these would hold up better. These bags are thick and sturdy. They're a little stiff at first but softened up quickly. They're great for exfoliating. The only change I would like to see is the wood closing bead changed to a locking clip as it slides open all the time.

Great product!
Color: Beige (8 Packs)
I buy handmade soap from a local soap maker, but I’ve always had trouble with it lasting—if I leave it in a soap dish, it never dries properly and melts away too quickly. I used to use loofah socks, but they were frustrating: the knots wouldn’t stay tied and they tore apart easily.
I decided to give these a try, and I’m impressed! I had a couple of concerns going in. First, I wasn’t sure they’d fit the larger-sized handmade bars I use—but they do! It’s a snug fit at first, which can make lathering a bit tricky, but after one or two uses it softens up and starts to lather beautifully—honestly, better than the mesh loofahs I’ve used.
The design is thoughtful: the knot stays secure, and the bead keeps the soap from slipping out—both huge improvements over other products I’ve tried.
The biggest surprise? The exfoliation. It’s effective without being harsh, even on sensitive areas. My skin felt softer than it ever did with sugar or salt scrubs. That’s an unexpected bonus I didn’t even realize I needed!
Highly recommend—especially if you’re using handmade or natural soaps and want to make them last longer.

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.
