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. The snap buttons are worn. They were used with urine pads, so some fibers and dog hair are attached to the Velcro, but the Velcro's strength is not affected. Would you like to try them out for size or as spares? Please understand that these have been stored at home before purchasing.
