Charm for bracelets (fits Trollbeads, etc.) - a three-tailed fox on a log.
In Japanese folklore, kitsune is a kind of demon. In this context, the word "kitsune" is often translated as "fox spirit". Any fox who has lived long enough can become a "fox".
Kitsune can have up to nine tails. In general, it is believed that the older and stronger the fox, the more tails it has. Some sources even claim that kitsune grows an extra tail every hundred or a thousand years of its life. However, foxes found in fairy tales almost always have one, five, or nine tails.
