Material: stainless steel,silicone,pu leather One bar prison device,adjustable height(including dildo height)is 75cm-125cm,adjust height as your wish and fix height by the screw on the bar. If you need other height of it,just leave a note to tell me when order. The top of bar has a vac-u-lock plug,can let you replace the original dildo with other vac-u-lock dildos if you need. If you need an extra sucker dildo base for sucker dildo usage, just contact me,charge extra $10. It has adjustable size leather ankle cuffs,fit most of people. My suggestion is to use any wrist cuffs and lock her hand on her back,then she has no where can go but only stand on dildo.
