Just like our washcloths, Soap Sacks are made with 100% cotton yarn. They are machine washable and very durable and will have a long lifespan when properly cared for. All are handcrafted in NC. Each one is made to fit half of one of our regular bars of soap. Exact size may vary. Colors are all assorted. If you are looking for a specific color contact us so we can check our inventory or create custom.
