This marble is a cool piece of Kobuki history, coming from a customer order that John created clear back in 2001, a great slice of marble history from the Kobuki Early Years! This is an extra special early coral reef marble from John, part of his 'ocean bottom' series, loaded with all sorts of gorgeous coral. But what really sets this one apart is the neat Kanji signature on the bottom of the reef! Only a small handful of these Kanji signed reef marbles exist, so don't miss this wildly rare opportunity for a killer piece of art glass marble history!
