Toxic-free? Yes, toxic-free! Yoni tampons, Yoni sanitary towels and Yoni panty liners are made of organic cotton and are therefore healthier and more environmentally friendly than their synthetic counterparts. Yoni menstrual products are made from 100% certified organic cotton. Nothing else. No plastic, no chlorine, no pesticides, because these kinds of fabrics do not belong in or next to one of the most absorbent parts of your body. Yoni products are biodegradable and therefore better for the environment. Yoni, the non-toxic option! Yoni products are animal testing free.
