If you like to keep very close watch over your sub - or your dom likes to know where you are at all times, you'll be able to make very good (and consensual, of course!) use of Master Series' Tracer Tracking Collar.

Once the soft padded 1.5"/3.8cm band is all buckled up around your or their neck, you can add your air tag or similar tracker (not included) to a special slot on the Collar. Want even more peace of mind? You can add a padlock (you'll need your own), too.

In vegan leather and nickel-free metal, the Tracer is easy to clean as needed - hand wash it for best results.

*Collar adjusts from 14-16.5"/36-42cm in circumference.
