Natey has made some awesome marbles over the years, and this one is one of the SWEETEST!! It features one of his killer thunderbolts on one side of the twist, along with an air trap implosion on the other side. A gorgeous opal floats on the tbolt side, and then to top it all off, it's surrounded by one of my favorite glass colors ever - Steel Wool, woooohooo!!! It is SUCH a sweet marble, one of those that you dream about when you think of cool marbles. Don't miss this rare opportunity at a Natey gem!! It is unsigned.
