I have one made by Yerba Prima. www.amazon.com/Yerba-Prima-Tampico-Skin-Brush/dp/B0002JFZDQ
. I just went to a store and found this one, so I haven't used any others. It took some of my skin a while to get used to it, but not for long. You may find your skin doesn't feel as dry after doing it since it removes dead skin cells. It's scratchy feeling, so you don't apply a lot of pressure when doing it. My arms were the most sensitive, but now it doesn't bother me. Others should chime in with suggestions for other brands.
