Reloading Shell Holder Holder

Neat little design I whipped up. I wanted to take a crack at designing one of these shell holders myself and I'm pretty happy with the result. It holds four shell holders, with enough space on the front to accommodate for a printed label for each holder as well as enough space on the back to stick on a 1/2" piece of velcro for attachment to various surfaces. It's a nice little thing to have if you're a single-stage reloader like myself.

Update: I've made a modification to allow for 10mm x 3mm magnets to be inserted and superglued in place to give the shells a little retention. Occasionally the shells would fall out if the holder was mounted directly to the bench and the bench received a good thud, so this option gives you a little more security if you'd like.
