A labret piercing is typically any piercing involving the lip, as the word 'labrum' refers to the lip, however it is also the style of jewellery. A labret stud has a flat back with the gem on the other end. The flat back sits flush to the skin, this reduces any potential risk of damage to the teeth. Labret piercings can also be used on ear peircings such a the helix, tragus or conch as the back of the piercing will sit nicely against the back of the ear.
These labret are internally threaded which means the jewel screws into the inside of the wire. This means the wire can thread through the hole, meaning it is less likely to cause any damage as the wire doesn't have a textured edge to it.
The 6mm and 8mm will fit the ear piercings well as they are quite short, the 10mm and 12mm are likely to have room to spare so are more suitable for lip piercings as it is a thicker area.
