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.

Nice addition
Color: yellow
These aren’t the most gentle but a good gentle exfoliation. They are thick enough to keep the soap in. Fits a normal bar soap easily. With the quantity included you’ll be able to share as you’ll not need many yourself since they hold up to washing very well. The color is a nice off white- natural looking.

All natural alternative to loofas
Color: yellow, Color: yellow
I love that they are all natural, plant based, and exfoliating. Mine is already starting to stink a little, so I’ve started making sure that I’m squeezing all the water and soap out after using and it doesn’t smell anymore lol. I prefer these over using loofa with microplastics. They are effective, strong, thick, and size is for small or regular sized soaps. If u have a bigger soap just use the soap first and then lather with this. You will still have to switch out every once in a while (like a loofa). Amazing value for price ⭐️
