Duncan - Big Fun An oversized blast at over 60mm, Big Fun is also designed for fingerspin play. It's rare to see an oversized yo-yo designed for fingerspin play, but the Big Fun is just that! Feeling one or two whole sizes larger than the more common "full size" yo-yos, the playfeel of the Big Fun is literally massive! Another bonus of the design is the special sidecap designed for fingerspin play. The smooth surface is designed to guide your finger to the center axle, making it easy to land the horizontal yo-yo onto your finger and keep it sleeping sideways. The body has a special design that prevents damage when over-tightening the sides. As you twist it closed, no matter how hard you twist the sides you don't have to worry about damaging your Big Fun. *This yo-yo may have some vibes, a result of the manufacturing and assembly process; adjust the gap by twisting the yo-yo open or closed to address this issue.
