Using the Exquisite Coquette - style Vegan Leather White Bondage Collar is super easy. First, open the back buckle closures. Then, place the collar around your neck and adjust it to a comfortable fit within the 13.25” to 16” (33 - 40cm) range. You can attach it to other bondage lingerie or accessories using the large metal opening ring. When it comes to maintenance, use a soft, damp cloth to wipe the vegan leather part clean. Avoid using harsh chemicals as they might damage the material. Also, make sure to keep the metal parts dry to prevent rusting. Always check the collar before each use to ensure the buckles and the ring are in good condition. Have fun and stay safe while using this collar for your intimate adventures.
