The Guppyfriend washing bag is developed to reduce the shedding of microplastic and prolong the lifespan of our clothes. When we wash garments made of synthetic materials, microscopic fibers of plastic are released into our lakes and oceans where they harm the environment and the animal life. The Guppyfriend washing bag collects the microplastic fibres during laundry and you can then dispose of them properly. The surface and material of the washing bag is gentle on the clothes during laundry and keeps them looking fresh for longer. Win win!
