Review (5/5): Buy these, you will be converted.
It took me a while to figure out what these were even called (my half Japanese boyfriend introduced me to them, but his mom was bringing them back from Japan....) and then to find them anywhere after that. I'll put it plainly: This is like a loofa on steroids. It's unraveled - so just a long rectangular strip, which is awesome because its makes it a lot easier to reach your own back, and the abrasion is much heavier - way better at exfoliating than those pansy little balls of fluff most people use. :) Easier to wash out the soap afterward as well!
