I no longer make any bullet pens or any weapon pens and have a bunch of empty brand new shells. Also have the bullets. Also somewhere I have the pen clips. I have both nickel and brass shells. My question before I put up for sale can I ship through USPS mail or do I have to ship UPS or some other service. ?? Do I have to disclose what is being shipped? What are the rules for this now that things have changed so much?? Also can you ship a completed bullet pen. I use to make these. What is the going rate for new shells these days?? How about the bullets. Full metal Jacket copper. ?? Any questions I would have to dig them out and take photos. they are unprimed too.
