The Strict Leather Black and Blue Locking Collar not only uses an eye-catching black and blue color scheme, but you'll enjoy wrapping this around your partner and making sure that they understand who is in total control. You can utilize a padlock (sold separately) to ensure that your partner is locked in nice and secure. The leather is comfortable so you can wear the collar for long lengths of time. There are also 3 D-Rings attached in case you want to connect the collar to cuffs, for example.
