What is the most cost effective way to ship brass? How best to package it so it all arrives... without leaving a trail of brass "breadcrumbs" behind out of a split box or envelope. I understand USPS won't take the tyvek envelopes more than 1/4 inch thick so that seems out these days. So what is an economical way to ship brass? SFRB seems expensive and limits quantity unless one goes with a medium box. And maybe some sort of internal packaging?
I have some brass, I'm thinking of selling it, and find at best maybe 120 fit into a SFRB which seems to me would be adding 5 cents per case to the cost just for shipping, without benefit to buyer or seller. Be nice if there was a way to get that shipping cost down. Any suggestions?
