I created a new product Czech-crystal bead charm with ringing bell.
There is a ringing bell inside the ball. Ball size is 2 cm. Black nylon strap can be attached to cell phone, camera, bag, zipper, etc..
6 different colors are available now at TinyShiny.com.
When I was kid in Japan, I had a key holder with ringing bell for my bicycle key. That way I could here the bell ringing whenever I dropped the key.
Today, I like to attach little charms to my bag and jacket, so that I can hear the little jingling bell sound everywhere I go.
