Here is an ultra rare collab, and the only one that I know of between Kobuki and DWreck! This is a classic in that it combines the talents of two of the oldest boro marble masters that we have. Derek was the first artist I ever saw creating imploded face marbles back in the early 2000's, and those pieces are now highly collectible as a result. Kobuki doesn't create faces, but took it a step further to create full heads, starting with his dragon heads way back in the early 2000's as well, and has now created a whole line of all sorts of different heads over the past several years. So, to bring these two legends together into one amazing marble is sort of a no-brainer, and yet here it is the first time we've seen it happen! Derek's awesome Master face, packed with SO much detail (THOSE EYES, THAT BRAIN!!) is paired up brilliantly with John's Minion head with glowing eyes and mouth. Ha ha, SO perfect! This is one for the history books, don't miss out!! Signed 'DRWECK 2016' along with John's Kanji signature as well.
