These are vintage Sleep Machines (circa 1998) that have been re-machined to accept Dr. Yo's Turbo Discs! Stringplay and performance are enhanced now that these yos don't require a "double loop!" Quantities are limited to the few dozen we found in an old box...act fast for your chance to own the World's First Ball-Bearing Wooden Yo-Yo, it's already a classic!
