Hi, Thank you for your inquiry! The edges of the Large Size Closet Laundry Kids Room Toy Organizer Foldable Storage Basket are made of soft fabric. In this way, it is both lightweight and very practical to use. However, thanks to the structure of the basket, it also has a certain durability when heavy items are placed inside.
