This is an ungimmicked set of professional thumb cuffs as used by many police departments around the world. When applied to the spectator’s thumbs, it’s impossible for him to escape.
But, when the spectator locks the thumb cuffs onto the performer’s thumbs, he’s out in a jiffy. The secret is simple yet little known. Audiences love escapes. Give them what they love!
Made in brass, chrome plated, and complete with instructions and carry case.
