1/4" (6.4mm) 14G Surgical Stainless Steel Screw-on Internally Threaded Straight Barbell Price for 2 pieces I purchased these at a studio and used them for about 5 months. They have been disinfected with alcohol and cleaned with ultrasonic cleaning. Since they were put on and taken off at the studio, there are no noticeable scratches to the naked eye. There is no backing card or case, so they will be placed in a zip-lock bag, wrapped in bubble wrap, and shipped.
