These beauties are made from high-quality, wood-free paper that consists of sugarcane fibre, linen, and hemp. They're also printed with certified compostable & vegan inks. These stickers are 100% compostable. Simply put them in your food waste bin, and they will compost within 12 weeks! Please keep in mind that this is a paper sticker, so it cannot handle getting very wet. It is resistant to scratches & is splashproof(water only, not oils); however, it's not advisable to stick your sticker anywhere it's likely to get wet (i.e., on a water bottle would not be ideal).
