I put all the small items like socks, glasses cloths, fabric belts, laces. They don't get lost in the wash or during drying. Water passes freely through the mesh so everything inside is washed normally. Very convenient also for clothes that easily stretch out, have zippers or buttons. They don't get caught in the mesh nor tangle with the others. It protects clothes from pulling and the drum from the impacts of accessories. It is essential in every wash.
