It is.........a pair of Yoho Superspins!
Pictured above are Two Yoho Superspin Diabolos and a pair of sticks with string.
Diabolo's diameter is 5 inches (12.5 cm).
Diabolo's height is 5.5 inches (14 cm).
Diabolo's weight is 296 grams.
These diabolos have ratchet axles which allow coasting of the axle on the string. Ratchet axles aid the diabolist in creating spin. One side of these diabolos needs to be near the performer for the ratchet engage during power pulls.
Amazingly these diabolos can be taken appart and stored in a 'spere' form with the aid of plastic 5 inch ring.
Sticks are Fiberglass and 16 inches (40 cm) long.
The Gray caps on the sticks clue you that this is a Diabolo Tricks set of sticks.
String is #18 braided black/white fluorescent nylon 27 inches (69 cm) long.
Length varies depending on diaboloist preference. See FAQ-String Length.
