Comfortable cuffs are important, but they also need to get the job done, securing your partner. I designed these with locking buckles, so you can use them alone or with a padlock for a little extra excitement. Nothing says you are Mine like the click of a padlock. -Mistress Isabella Sinclaire  Made of durable, premium leather with a supple yet durable feel, these premium cuffs feature silver hardware, nickel-free metal, and an optional locking buckle for extra security.

Each piece reflects her style, sophistication, skill, and class.
