We’re excited that you asked! We’re proud to say that our tampons are 100% organic, GOTS certified cotton. The string is also 100% organic GOTS certified cotton with a water-repellent wax coating. Our applicators are made of a plant-based plastic material. Each tampon is sealed in a compostable wrapper. And, to top it all off, we’ll ship it to you in a compostable mailer!
