Silicon lined cuffs
We have these metal wrist cuffs for girls (small size) and they are pretty nice! But what makes them even better is the silicon liner, which means you can wear them for days without problems! There’s black, blue, and pink silicone! Which one would you prefer?
The Korean company Yuil makes regular-style steel handcuffs with a silicone lining for comfort. They have both hinged and chain models. I got a set recently, they’re quite good.
