This is the Locakable Slave Collars and Padlock Collar menus.  Please choose from the menus below.  The first menu offers Leather Collars with Padlocks as an accessory but not for Restraining.  These collars have a buckle and eyelets in the back and therefor are adjustable.  The 2nd menu has the Lockable Slave Collars.  Some of these designs need an EXACT fit as the lock is the sole fixture for fitting the collar onto the neck.  Other Locking Slave Collar have eyelets for adjustment, but a Locking Stud in place of the Buckle, and is therefor adjustable as well as functional.
