I'm not saying it happened here, but many people do not understand that you have to put things in appropriate packaging for the machines to process. It saddens me every work day to see what is thrown out of the machines without the packaging it came with. No address, no delivery. Only paper goes in envelopes for example. Not hard items. Not keys. Not pens. Not coins. Not makeup you want your friend to try. Not anything but paper. And that is because it has to go around hundreds of steel rollers, held between high speed belts for sorting. If you have a hard item, put it in a flat bubble-wrap protected envelope for protection and processing through the Automated Package Processing System machines, or, better, in a well-taped box with an address written on the box. And NOT a tiny box. Heck, if you have ANYTHING that is very important, put it in a flat or a box and make it bigger than the item by far. And let me say that only a very tiny percentage of the 156 Billion pieces of mail the USPS processes every year is damaged, destroyed or lost. And most all of that is due to improper packaging of items. Think before you send because people don't route mail anymore, multi million dollar machines do, and at high speed and accuracy.
