Cotton soap savers are eco-friendly and perfect for preventing waste of leftover pieces of soap, why not ditch the plastic bottles of shower gel and hang one of these beauties in your shower! Made from a 100% cotton, not only are they great for the environment but will save you money too! Soap not included. Machine washable. The soap socks are big enough for your average bar of soap but there is some stretch in them to accommodate a larger bar.
