Simple + dainty delicate silver stud set on a threadless pin for easy and painless insertion into your labret post. Sold as a single. (one top + one post). Material: 6Al-4V-Eli ASTM F-136 Titanium Size: Moon: 3.5mm Star: 3mm Heart: 3mm Lightening Bolt: 5mm Color: Silver Directions for use: separate top from labret post by pulling straight out. Insert the labret post into your piercing from the back. Simply push the pin on the back of the top straight into the labret post until you feel it secure. Give the top a small tug to make sure it is secure in place. If the top is not securing into the post at any point, remove jewelry (this is easiest to do while it's not in your piercing) and insert only the tip of the pin inside the post and bend the pin a very small amount, and retry until the pin secures inside the post better.
