Coloured scanning electron micrograph (SEM) of a hooks and loops fastener. It is a two-sheet material which is used as a reversible fastener on clothing and fabrics. One sheet consists of loops (pink, upper frame), the other of hooks (red, lower frame). Note the loops that are attached to the hooks. This allows a secure grip, yet one which can be easily undone. Magnification: x7 at 6x7cm size.
