Great natural fiber soap bags
I'm a soap maker who lives with teenagers who always seem to get everything absolutely soaked in the bathroom. I invested in these bags as a way to help my soap last longer while providing some scrub without adding exfoliators to the formula.
They are well made, a good value, and I love that they are made out of natural fibers. They dry out quickly, are not too rough, but still provide nice exfoliation.
I will definitely purchase again.

Great, small investment
This set of bags was a great value for my money. Soaps all sizes fit in there perfectly. This is a very versatile item. I use one of mine in my bedroom for dry garbage like gum, wrappers and tissues, then empty it weekly. It’s a great quality. It’s all natural very durable. And the main reason why I got these is because they also exfoliate.

Nice bags for a good price.
The bag works well and I like the way it closes. If it was a little bit bigger where the soap could move freely I would have given it 5 stars.

Great bags!
Great quality and amazing for my shampoo and conditioner bars. Love no plastic! They dry great hanging in the shower. 3 months so far and no mold or mildew.
