Great For Relieving the Worst of Itches [SEP] I got these after running into a nest of seed ticks and finding myself in a constant state of itch for about a month.  Using these in the shower on my skin was one of the few moments of relief I had.  These contain a piece of loofa stitched very well onto a cloth pad with a piece of elastic over the back to keep on your hand. I didn't realize until recently that loofas are made from the dried insides of gourds. So, no, they're not a product of the sea like a sponge. It's amazing to me that they're able to be stitched so well into cloth.  I really like these. I just read that it's possible to machine wash loofa but that you shouldn't put them through the dryer. Eventually, my loofa got moldy from hanging out in the shower so often. I threw it away, but next time I'll know that I can put it through the washing machine before it gets to that state. Luckily, this is a 3-pack.
