These sisal soap saver bags are an excellent value and very well-made.
They feel sturdy yet remain pleasantly soft on the skin during use. Keep in mind that they do arrive with a very strong natural grass smell right out of the package. I highly recommend washing them in a water and vinegar solution, then letting them air or sun dry before your first use. Once the smell is gone, they are absolutely perfect!

I prefer a thinner bag for soap. They are too thick for me.
Not what I thought they would be

The SCRUB
Color: 2 Pack
Perfect amount of abrasion for a mans skin. Gets all the dead skin off, without leaving red marks. it does eat your soap faster, but that just means you're cleaner or something, right? Anyway, great product, came as expected, didn't fall apart yet after a month of use. Very easy to use just throw your soap bar in there, and leave it in a wire basket to dry off after your shower.
