This is a limited edition ring created by Mr. KING, the founder of TADY&KING. It's an extremely rare ring with the KING name engraved on it. I purchased it around the year 2000 at Mr. KING's workshop in Koenji, before the RESIST store was established. It is undoubtedly authentic. First come, first served. I've been a TADY fan for 30 years, but I'm no longer at an age where I wear accessories, so I'm passing it on to someone who loves TADY.
