This is one of the first two collabs that Yoshi has ever created with Kousuke Oyama, aka Kinoko Heads. That in itself is awesome enough, but on top of that, it actually features a Yoshi MARBLE that is leather wrapped by Kousuke! AND, the marble actually moves inside the leather, so you can turn it around and see all the sides of it! It is tight so it doesn't just spin around, but is the perfect tightness for viewing. And WOW, that leather wrapping is on another level! Soooo many tiny pieces of leather were stacked together to create that amazing pattern you see on the sides there. It is an intense many-day process, pulled off by the one man in the world who is doing this sort of thing with leather. What I truly love is how well the design matches the beauty of Yoshi's marble. The marble is a gorgous little gem with multiple layers and threee opals stacked inside of it. Saying this pendant is legendary is actually and understatement! This piece is signed by Yoshi via his signature YK opal inside the marble.
