We make this BDSM neck cuff in custom-made sizes from real, high-quality leather. Its width is 4.5 cm. We solved its lockability at the back with a padlock. It is decorated with 3 screw rings located in the front and on both sides. We covered the place of the screw rings inside, so it is not visible. It is a custom-made product, so it is important to specify the exact sizes, based on the attached photo.
