Post material: Hypoallergenic titanium (these are lead free and nickel free). Posts are 21 gauge (standard piercing gauge), we supply butterfly backs with the small hoops, and larger plastic backs for medium and large hoops.
Shipping: $4.00 flat rate shipping (USA) for as many pairs as you like. International shipping base rate stays the same no matter how many pairs you order.
