It's a worry stone. This one is almost like a coin, but a bit thicker. It has an Ultem core surrounded by crosscut vintage micarta. It has facets and smooth edges that make it very fidget-able.

*I make these for fun. They are completed, then I use them as props in pictures. Then I drop them in a cup on my desk. Eventually I list them for sale here. They'll probably have dings on them. That's part of their unique character and is not considered a flaw. They're fun, and have A GREAT PERSONALITY!
