This 3/8" leather collar is delicate and discreet. It's narrow enough to be worn day-to-day as a choker or day collar, but still has the look and feel of a traditional BDSM collar, and locks in the back with a small, working padlock, plated to match, which is included. This soft black calfskin garment leather is double stitched and reinforced while the hardware is nickel free, plated in brilliant rose gold with a clear finish for long wear for your sub.
