Hook-and-Loop is a sew-on fastener. Hook-and-Loop tape is often called "Velcro", but Velcro is just one brand among many. The brand of Hook-and-Loop we carry are Touchtape and Sahara. Our Hook-and-Loop sews smoothly, holds up to lots of washing, and does not fray. Touchtape Hook is really strong - very difficult for toddlers to open! Sahara tabs are favorite way to make diapers easy to open and close, preferred by dads and grandparents.
