666, the number of the...meat? 

Measures 1.8" wide and 2.5" tall

Laser cut and engraved from 1/16" two tone engraving plastic, the same type of material used to make livestock identification ear tags

These can be worn several ways! The 12mm black studs are removable from the tags and can be worn on their own as black studs that mimic the look of a 00 gauge plug, or wear one stud on one ear and the tag on another, or wear tags on both ears, the choice is yours!
