I no longer need these since I switched to disposable diapers. They are made of denim-style mesh material with snap buttons. They have been washed several times. There are scratches on the snap buttons. They were used with urine pads, so fibers and dog hair are attached to the Velcro, but the Velcro's strength is not affected. Would you like to try them out or use them as spares? Please purchase only if you understand that they have been stored at home.
