I definitely remember them, just hadn't thought about them until I came across this, lol.
I had several of them, all different colors and designs. The fad didn't last all that long, but they sure as hell were fun.
Just after I wrote my stories about my cabbage patch doll and pound puppies I knicked down to the supermarket. While I was there I saw a slap band. I purchased it of course (I also put it as the group logo)!
