- Washing net in untreated polyester (PET) color white - Zip closure - Dimensions: 50 cm x 74 cm - Made in Europe - Fiber-safe material Synthetic garments release micro-particles of plastic into the environment when they are washed. These particles then end up in rivers and oceans, damaging the environment and our health. However, using the GUPPYFRIEND® wash bag effectively prevents this problem: the bag reduces the dispersion of fibers during washing, thus protecting your clothes, and reliably filters out microparticles before they pollute the water. It's a win-win solution for you, your clothes and the environment. We recommend using this washing net to wash Polyester items and recover any micro-plastics that may become detached from the fibers during washing.
