Finesse Juggling Diabolos. The size of the Finesse model is considered the standard, preferred by most experienced diaboloists. The 5" diameter strikes the optimal balance between a size large enough for good visibility without being too large for complex moves. Well balanced and very durable, manufactured in lightweight, flexible translucent elastomer. Polyamid center cones for greater wear. Parts are matched before assembly to assure balance for smooth spinning performance. Each diabolo comes handsticks. String is custom braided polyester cord for long life and smooth action. Two strings and a basic instruction sheet included.
