A slap bracelet (or snap bracelet or slap wrap) is a bracelet consisting of layere, flexible stainless steel bi-stable spring bands sealed within a colorful fabric cover. The bracelet can be straightened out, creating tension within the springy metal bands. The straightened bracelet is then slapped against the wearer's forearm, causing the bands to spring back into a curve which wraps around the wrist, securing the bracelet to the wearer. The slap bracelet was a popular fad among children, pre-teens and teenagers in the early 1990s and was available in a huge number of then-popular patterns and colors.
