This is a set of 20 surgical stainless steel ball catches for body piercings (16G 3mm screw type). I accidentally bought a large quantity, so I'm selling them. All are unused. If you would like to combine with other items, please contact me via comment. Due to shipping costs, I cannot sell them individually. If you have no questions, you are welcome to purchase immediately. Material...Stainless steel Scratches/Discoloration...None
