Hook and loop tape, also known as Velcro, is a simple fastening method that offers strong grip and easy detachment.  Each strip has two sides; one with hooks and the other with loops. When these surfaces are brought into contact, the hooks interlock with the loops to create a secure attachment. These 25 metre rolls of adhesive backed hook and loop tape make work well on different surfaces. They are available in black and white, with widths of 25mm or 50mm.
