S&M Shadow Locking Cuffs

The metal feels sturdier than I expected for the price, and having two keys included is a nice touch since I always lose one. They stay put during use and don't rattle around, which was my main worry.

The locking closure clicks in solid and stays put, which is exactly what I wanted. Both keys work smoothly and the cuffs feel durable without being bulky.

Wasn't sure how sturdy these would feel for the price, but they're solid and the keys turn smoothly every time. The locking closure keeps everything exactly where I set it, no slipping.
