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 did not realize until recently that loofas are made from the dried insides of gourds so no they are not a product of the sea like a sponge it is amazing to me that they are able to be stitched so well into cloth i really like these i just read that it is possible to machine wash loofa but that you should not 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 will know that i can put it through the washing machine before it gets to that state luckily this is a pack
