Our Safety Buckle Lanyard is made of nylon. The nylon strap is black and gray, with a smooth and shiny surface, which looks high-end and elegant. The nylon material is soft and skin-friendly, and it will not strangle your neck when worn around your neck. The nylon strap is equipped with a detachable plastic buckle in the middle, and the end is a black rotating dog buckle, which adds a sense of luxury when paired with the nylon strap.
