$3.34 on Amazon.com (I found mine at Ulta, and I've seen similar items at my local grocery store in the Beauty/Cosmetics dept.)
This loofah is my new favorite shower item! I get pretty bad red bumps after shaving, and my skin can look a little dull, especially on my legs. I knew exfoliating would probably help, but just hadn't found the right product until now. This loofah pad is cheap and long-lasting, and it works wonders on my body! Rub soap on it and then rub wherever you need some exfoliation. Apply more or less pressure, or scrub for more or less time--it's simple but effective. And it really has helped with my shaving bumps. I like that when it gets icky or worn out I can just toss it (the idea of a wet loofah growing germs and getting gross in the shower kind of skeeved out out initially, but it seems to be doing just fine after a month or so in the shower). There are fancier options out there but this one works just fine. I love this product so much that I might even give them as Christmas gifts (with a little handmade soap included with it!). My only complaint is that it isn't as exfoliating now after a month of using it every day, so I threw it away. They're supposed to last a few months, using it a couple of times a week, but I was using mine daily. And it probably would have still been scratchy enough for some people, but it's only $3 for a fresh one. I'm definitely going to keep repurchasing these.
