The Valma ECO Pop-Up sponge is a 100% natural sustainable and reusable cellulose sponge. The unique Pop-Up sponge is compressed into a very thin, flat disc with minimal dimensions. As soon as the sponge comes into contact with water under the tap, it starts to expand to its true size of approximately: 16x10x4cm. The scratch-free Valma ECO sponge has a high absorption capacity and is ideal for indoor and outdoor use for washing windows or the car, for example. Rinse the sponge thoroughly before and after use. After use, the sponge dries hard; for reuse, hold the sponge under the tap and it is ready for use again. The sponge is 100% biodegradable. So after months or years of use, it can simply be composted, without any harmful effects. Valma Eco friendly - Sustainable cleaning starts here.
