I'm trying to help a friend fix her favorite pen. It is a Mary Kay pen and the twist mechanism broke. The pen has a lot of meaning for her and she was heart broken when it broke. The twist mechanism's outer diameter measure 23/64 and is 1 1/4 inches in length with male threads. If I could figure out how to up load a picture I would post it. So I'm open to a little education on how to do that also. If anyone has any idea of a pen kit that would have this mechanism or know where I may order spare parts that would fit, I would appreciate any help. Thanks
