Another recent basement find. This was part of a series of keychains featuring the Japanese female pop duo Puffy. They eventually changed their name to Puffy AmiYumi when they promoted themselves in the US because of possible confusion or legal trouble with Puff Daddy whose nickname was Puffy. But then Puff Daddy became P. Diddy, and then just Diddy. .
Puffy never stopped being Puffy in Japan, though.
This item appears to be worth about $15 or more, but I wouldn't sell it. It's sentimental. The first Japanese song I sang at karaoke was Puffy's "Ai no Shirushi."
