Review (4/5): I'm a dude and these are pretty good
I don't know anything about the other reviews that talk about the original Salux from Japan versus impostors from China. I've never owned a product like this before. I am male and have sensitive skin that's prone to irritation that results in random pores getting clogged on my arms or chest or legs. I bought these on a recommendation to test out and see if they helped. I've only had them for a few days, and can't really say yet if they've done anything for my pores or not, but they do seem to be doing a really good job at exfoliating my skin.
The individual towels are roughly 12 inches wide by 24 or 30 inches long. They're made of some sort of woven nylon or plastic material that is kind of wavy and extremely abrasive when rubbed across the skin. You use the towel by putting a dollop of liquid soap onto it and then rubbing it onto your body to create a lather. The towel is long enough that you can easily scrub your back by holding the ends of the towel and pulling back and forth. The towels are abrasive enough that it really feels like you're scraping a layer of skin off. Probably not appropriate for use anywhere sensitive.
I'm loving these so far. Highly recommended.
