The design that redefined yo-yos, now improved further by the Speed Explosion axle fitted as standard. Also compatible with Slider, Woodoo & Shockhead axles. Extra large, springy half-shells in bright colours. Butterfly shells make it great for string tricks but also great for looping. Hubs in Anodized Silver finish.

As with all Henry's YoYos, the Viper is fitted with the patented 'Quick-Trick' Adjustable Axle Width System - simply twist both shells and the gap will get wider or narrower.

Shells in red, yellow, green, purple, blue, turquoise, orange, black, clear or luminous (glow in the dark). Diameter 66mm, width 35mm, weight approx 51g. All Henrys YoYos now include the Markus Springer YoYo trickbook.
