Sei Mio Cross the Threshold X-Shaped Door Restraints

What happens behind closed doors gets a lot more interesting with Sei Mio's Cross the Threshold in your scene!

This criss-cross door restraint system turns an ordinary door into a full-body control point the moment it shuts. No extra furniture, no complicated setup, just instant structure and a very clear shift in who’s in charge.

Four adjustable straps run over the door and anchor securely at the top and bottom, creating a stable set-up as four soft Velcro cuffs (two for wrists and two for ankles) clip to sturdy rings on the strap ends.

Setup stays quick, removal stays easy, and when the door opens again, everything packs away neatly. Until then, whatever happens back there stays between you, the straps, and the view.
