Ramie is a plant in the nettle family originating in asia, and is used to make the fibers in this puff. It is extremely soft, and a great way to exfoliate naturally. Please wring out after each use and let hang dry. These are made from natural plant fibers so they are not like the nylon / plastic ones you purchase at most stores. They can be cleaned with a bleach water solution once a month to prolong the life.
