These sets 35-cm Diabolo Handsticks are available in Carbon and Fiberglass.
Fiberglass is strong and flexible and it absorbs shock. The fiberglass is covered with a plastic tubing to protect users and prevent fraying of the string.
Carbon is stronger and more durable than fiber glass but provides less flexibility. It is recommended for more advanced users.
This set of 35-cm handsticks come with two 4-m strings.
