All models are constructed with polyamid center cones for greater wear. Parts are matched before assembly to assure balance for smooth spinning performance. The handsticks (19.25 inches long) are hardwood in white gloss finish with special braided nylon cord for long life and smooth action. Available in five models: Finesse, Performer, Harlequin, Millenium and Arlequino. The 5-inch size (Finesse and Harlequin models) is generally considered the "standard" large diameter, preferred by experienced diaboloists. The Performer is a super sized model, for performers who want a really huge (although somewhat heavy) diabolo. The Finesse, Performer and Millenium models are made from light weight, translucent, synthetic elastomers. The Harlequin and Arlequino models are made from natural rubber. The small sized Arlequino is great for young people. Please Note: Each diabolo includes a handstick set, additional string and a basic instruction sheet. Swiss made.
