Normally, nunchucks can hurt when you hit them against someone else (or yourself). But with quarter inch of foam padding over a lightweight PVC plastic core, you will be hard pressed to injure anyone just by hitting them with the 12" handles.
The foam nunchucks come with a 5" connector that is either made from durable black nylon paracord or steel chain. It won't be a surprise which one, because you'll choose that when you place your order. The handles also have a golden dragon design (this may have some imperfections).
Order your own safe foam padded nunchaku and start practicing your forms with the assurance that you won't accidentally hurt anyone or anything.
