Where can you get a Buddha bracelet in the UK?

I don't know about in the UK, but here in Tokyo, I met a Buddhist monk on the sidewalk while riding my bicycle. He stopped me and gave me Kai guang Amulet and a bracelet. He taught me the meaning of Buddhism as well.

He was collecting money for charity so I gave him all the coins in my left pocket at the time, and I felt really good about doing so.
