Velcro is a fabric hook-and-loop fastener. It consists of two layers: a "hook" side, which is a piece of fabric covered with tiny hooks, and a "loop" side, which is covered with even smaller and "fluffier" loops. When the two sides are pressed together, the hooks catch in the loops and hold the pieces together.When the layers are separated, the strips make a characteristic "ripping" sound.

Available in 25mm and 38mm (38mm in black loop only)

Nappies and covers require a 1:3 ratio of hoop to loop velcro.
