Our sponge is made from 100% sustainable PEFC-certified cellulose. It is therefore not only vegan, but also biodegradable. It can vary slightly in shape - don't worry: that's in its nature. You can also safely dispose of the paper packaging in your waste paper. For our pop-up sponge, we only use vegan, water-based colours that have been certified in accordance with the Global Organic Textile Standard (GOTS).
