Snap Bracelets

What Is It?

They were popular in the late '80s and early '90s.  They were bracelets that start out in strip form...then when slapped against the wrist they would form into a bracelet.

What Happened?

They have a base of stainless steel (covered in fabric) so often the cheaper models would break...leaving exposed steal to slice up wrists. 

Aftermath?

They tend to try to make them safer I believe, there were warnings issued about these but I don't believe there was a recall.
