This listing includes; (1) Titanium Matte Black Locking Day Collar, one allen key, and two spare screws.

Introducing our latest design: a sleek and modern 6mm Titanium Matte Black Eternity Collar, perfect for those seeking a hypoallergenic and durable BDSM accessory for 24/7 wear. Crafted from high-quality titanium with a matte black finish, this locking infinity collar is both lightweight and incredibly strong, ideal for sensitive skin.

*New Design Lock: This item features our updated locking mechanism, a new design which includes a hidden sunken screw that does not fully pass through the cuff/collar. This gives you a tighter and more secure locked fit.

To Measure: 

Wrap a tape measure around the thinnest part of your neck. Add 1/2-2 inches depending on the fit you are looking for: 1/2 provides for a choker style fit, while 1 to 2 inches will for a slight drop below the neck line.
