I create magnetic holders for eyeglasses, I.D. badges, and keys. The most popular application is for scarves. It is a great way to tie off a scarf and hold it in place.
I have been creating this for that past 12 years. Last year I was finally granted a patent for the holder that I use. I re-purpose a variety of jewelry pieces from very small pieces for glasses or ID badges to larger pieces that hold larger scarves/wraps.
