This is a set of 6 pair (12 pieces) of new polished aluminum screws for Capital plastics mint sets, proof sets, currency holders, and individual coin holders.  (Holder and coins obviously not included!)  Make your proof set really POP, with even more great eye-appeal!   They are much stronger than the cheaper plastic screws, (which tend to strip out and break easily!)    Plus, FREE SHIPPING & POSTAL TRACKING!  Also, please check out our other screw set options, including solid machined brass (gold color,) and antique brass!  And check out our early choice and gem mint sets we currently have listed, as well as individual coins! If you have any questions at all, please email us through the "ask the seller a question" button, located at the top of this page! Thanks again!  Respectfully, Chris
