Slap bracelet
A slap bracelet (or snap bracelet) was a bracelet invented by Wisconsin teacher Stuart Anders in 1983, sold originally under the brand name of "Slap Wrap". Consisting of layered, flexible stainless steel bistable spring bands sealed within a fabric, silicone, or plastic cover, it can snap around a wrist when slapped on it with some force. It can have many different colours and/or designs.

History
Original Slap Wraps had been 23 cm (9.1 in) in length, 2.5 cm (0.98 in) wide, and made of steel that was 0.15 mm (0.0059 in) thick; although, cheap knock off versions had used thinner steel, which was more likely to break and/or cut the wearer, the dangers of which first came to light in 1990, soon after they were released.[1]
It was a fad among children, pre-teens, and teenagers in the early 1990s. It was available in a wide variety of patterns and colors. The bracelet was banned in several schools following reports of injuries from worn out or modified versions.[2][3]
In 2018, different slap bracelets were recalled: "The slap bracelet’s metal wristband can pierce the protective fabric around it and expose sharp edges, posing a laceration hazard to young children."[4]
