I bought some body jewelry that had been not used but taken off the packaging to ship in a smaller envelope. I have no idea what gauge they are or anything like that. The person I bought them from told me they are surgical steel. I have 21 pieces of body jewelry for eye brows, nose and lips. They have different colored crystals in them (as you can see in the pictures). I am asking for $5.00 apiece. I have 4 larger pieces I think for belly buttons for $8.00 apiece. I also have 2 butterfly belly button pieces for $9 (for smaller with blue crystals) and $12 for the larger with rust colored crystals.
