The Blackline Labrets come with a 3mm ball.

Just as with all of our other Medical Grade Blackline items. The coating is permanent, so there is no need to worry about it wearing off. And it is placed over Medical Grade Titanium Jewelry, so there are not even any alloys such as nickel. Our Blackline is truly one of the safest and most advanced pieces of body jewelry available anywhere. The PVD coating is already used on pacemakers and other implants.
