Now you can mark your brass the same way the Indians marked their arrows. This is a great way to separate your brass from someone else's. This will allow you to maintain consistency when reloading. You don't want someone else's junk mixing in with your brass by mistake. Marking your brass is also a fun way to show your support. This device makes it easy to do thin blue line and thin green line to show your support for Police and Military. You can mark up to 7 different locations on one case. It can be used as a hand held unit or mount it the end of your table.
