This special handcuff is made of stainless steel and is not only super beautiful, but also really restrictive. Regardless of whether you are using the ball handcuff to fix your victim's hands in front or on their back, with the palms still up or down - freedom of movement is now a foreign concept.
Due to the flexible mounting of the four brackets on the rings, the ball handcuff not only adapts optimally to the anatomy of the respective victim, but it can also be folded up and stowed away to save space before or after use.
