Hey someone saw my post!!
The Rayma bracelet or the Q-Ray is sold as a health aid. It is supposed to be "ionically charged" and it balances out the electrical charges in the body. Aches and pains go away etc.. That what they say, I DON'T belive it. I wear it beacause it looks good and it is from Spain (anything to talk about Spain!!). Here is the site if you want to read more.

The bracelets come in different models. Mine is the "classic" I love it.
Like i said, its a great souvenir.
