This is a laundry net for shoes. I used it only once. My child's indoor shoes became clean. My child has entered a new school and the number of indoor shoes has increased, so I no longer use it. It's clean, so you can still use it. (The following is a quote from the website) Wash your shoes thoroughly! Just put them in the net and wash them in the washing machine! You can easily wash troublesome indoor shoes in the washing machine. The special brush inside the net removes dirt well and has a cushioning effect. The brush is a high-density brush that is finer than hair. It scrapes off dirt. It comes with a hook so you can hang it up to dry. Made in Japan from thread to product, for peace of mind and safety. ■Size: Approximately 25cm x 38cm ■Material: Body/Polyester ■Contents: 1 piece ■Product weight: Approximately 120g ■Country of origin: Japan Thank you for viewing.
