Designed by Duncan Crew Japan member and 2011/2013 European Yo-Yo Champion Kohta Watanabe, Strix™ features a modern shaped profile for wicked performance while performing today's most difficult string tricks. The latest in Duncan's De-Luxxe™ series of aluminum yo-yos, Strix features a large high speed ball-bearing axle, precision machined aluminum body and SG Sticker™ response for professional unresponsive yo-yo play. Disclaimer: Strix is for experienced yo-yo players and is unresponsive. Meaning that it does not return to the hand when you tug the string. To bring the yo-yo back to your hand you must do a "bind". Instructions are included.
