This is the nicest of Kobuki's ocean bottom reef marbles that I've sold yet, with a bright orange star fish on the side, and lots of his best and brightest cane. It's also a nice large size for this style of marble - really, if you want the best example of this for your collection that you can find, then this is the one. It is unsigned, showing that it was pre-2003, before John signed his work, now highly valuable as a display of early brilliance from this legendary glass artist.
