Alien Skin thickness choice The ring works great forThe Alien Skin ring is a flat profile ring that has the unique looking finish. Although the photo doesn't do it justice, the finish is made up of random lines of swirled texture. The lines seem to move as the light is shifted. The finish is smooth to the touch, so the ring is comfortable. The ring shown is 9mm. Alien Skin can also be specified to go on any of the other rings. You would simply choose that ring and pick Alien Skin as the finish.
