The Bujinkan symbol is for a martial art.
Commissioned as a surprise birthday gift for her husband, this Silver Bujinkan Symbol Pendant is to replace one that he lost. A number of years ago he bought his wife some earrings of this symbol, and bought himself the pendant to match. However, having lost his pendant, he liked the idea of a replacement.
As a martial art they used to do together, she thought it would be amazing if she could make this happen for him.
You can have this made to order just for you.
