One set that ties the wrists to the thighs and keeps them there. Padded cuffs at each point, joined by adjustable straps, so the position holds without anyone having to hold it.
The whole thing buckles on over clothes or skin and adjusts at every strap, which means it fits a range of bodies rather than one. Soft-faced throughout — this is a restraint built for a long session, not a quick photo.
Part of the Sei Mio range: understated, well-finished bondage gear that does not look like equipment when it is sitting on a chair.
