An eco-friendly, plastic-free, all natural Konjac sponge. An alternative to single use plastic sponges. Perfect for anyone aspiring to a zero-waste lifestyle. What are they made from? Konjac Plant Root - the root of a konjac plant and is hard until moistened, when it becomes silky soft. Vegan alternative to a natural sea sponge which, believe it or not, is actually a living creature! Beautifully gentle, even soft enough for babies and great for applying facial washes and even for removing make up. When you are finished with your Konjac sponge, it is compostable and biodegradable.
