Three Bluebirds
Three Bluebirds' cloths are 70% FSC wood cellulose and 30% organic cotton (GOTS and OEKO-TEX certified), printed with water-based inks - 100% natural and compostable, with no plastic. The whole product category is a plastic-free answer to both paper towels and synthetic microfiber cloths, and the brand sticks to it.
