These are, in our opinion, the best value carbon sticks on the market. Exceptionally strong carbon has been used with a signature slick surface - this means less friction and longer grinds, ideal for diabolists who like their diabolo play full of string tricks and technical contact. Super-Grind sticks are also exceptionally light which can aid 'suicide' based trick routines. The super grind sticks come complete with a length of string - enough to get started, but with regular use this will need replacing. 32 cm long with foam handles - string is secured through the handle body.
