OK Kobuki fans, if you want a rare and special marble, then this is one for you! This is an early ocean bottom marble from John, really nicely done, lovely design, tighty tighty craftmanship that was SO far ahead of his time. But what makes this marble truly special is the backside. John didn't sign his pre-2003 marbles, however, for a few special ones like this one, he signed the marble in Kanji in glass, underneath the surface worked into the design of the marble. Super, suuuuper rare, don't miss this one!
