The Sei Mio Doorway Play Adjustable Over Door Cuff Restraints - Black is kept here because restraint, done quietly, is an act of considered care — for the body wearing it and the hands using it. Sei Mio understands the weight of the brief.
Made in nylon, pvc — finishings that won't catch, hardware that holds.
Every bondage piece on Soft Hum ships with the same soft reminder — agree on a word before you begin, agree on a way out. The softer something looks, the more carefully it should be played with.
Kept in the black family.
