BDSM, submission, punishment, constraint are all practices that will interest your clients, especially if you present this rigid bar with 4 handcuffs. 
Presented by your Fetish Temptation Wholesaler, this set of submission or constraint, the partner will be held to a bar by the wrists and ankles forcing him or her to have a position leaning forward, enough to imagine several scenarios. 
To be comfortable, this set of 4 handcuffs is adjustable. 
The handcuffs have a carabiner attachment system, so these handcuffs can be used for other naughty games . 
Once in place, the handcuffs and the rigid bar will become one, “imprisoning” the person.
