I sold a vintage Surefire E1 in gunmetal finish. When I got ready to package it for shipping I found a round shipping tube with plastic ends that I taped snugly in the ends of the tube. The tube was about the diameter of a paper towel roll. It had been used to mail a rolled educational poster. I cut the cardboard roll down to about siz inches long and used the plastic ends. I wrapped the light in paper, inserted it into the tube, secured the snap-in plastic ends and taped them in place. Then I addressed the paper label with a return and deliver to address. I taped it to the outside of the tube with both addresses showing. I then taped the label until it was covered complately and the ends were taped in place so that they were mega secure. Then I mailed it. The E1 inside has never been seen since. The tube was lost in the mail. I refunded the money I'd gotten for the light. So if anyone sees a tube with an E1 inside it then most likely it's mine. As of now it has been mising for three or four weeks.
