From the Tom Kuhn website for the Roller Woody:
"Sometimes referred to as the Stradivarius of yo yos, this seemingly traditional classic profiled wooden yo yo is made of solid [not laminated] hard maple wood for its superior stability, durability and weight. This model is coated in gloss blue and then enhanced with a narrow white stripe.
Under the hood however, this is the worlds most technologically advanced wooden yo yo. This precision tuned instrument sports a precision ball bearing axle for undreamed of spinners (up to 10 times longer than regular fixed axle yo yos) and a super advanced, patented, adjustable string gap feature for fast tune ups allowing maximum play ability and features Dr Yo's patented Turbo Disc technology for optimum predictability. A beginner's confidence will build quickly while more advanced players will blaze new trails in the art of yo-yo play."
The Roller Woody was first introduced in 1991. This version came in a nice, large display box.
