Our wash bags have been designed to go along side our baby wipes and dry wipes, they are helpful for carrying around the wipes wet or if they are dirty. The wash bag can also be used for other purposes such as traveling. Our wash bags are usually a cotton outside or a harder wearing fabric with a waterproof insert. The lining has been donated to us from factories, clothing alteration companies or customer donations to save it from going to landfill. The wash bag is durable and if needed can be hand washed or machine washed.
