Wyvern Oroborus

World Yield Ventures in Evolution Research and Nanotechnology (W.Y.V.E.R.N.) chose the Ouroboros as a logo representing the cycle of renewed life, creation/destruction and eternity. But what does a Wyvern represent? Product Details The Wyvern Ouroboros bracelet is cleverly designed with multiple hinges to allow it to open, close and bite its own tail as a proper Ouroboros should. Like every Monkey Wrench piece, the attention to detail and the patina finish on the piece is impeccable. It's available in three sizes (S, M, L), each scaled in thickness as well as length so the proportions stay right — S for smaller wrists, L for larger.
