Trading Tip Mail securely. Putting a card in a penny sleeve and throwing it in a floppy envelope is not secure. You might laugh, but it's happened to me more than once. Needless to say, that was the last time I traded with them. On the other extreme, don't wrap cards so tightly in tape that they can't be accessed without damaging. You should leave some breathing room to let the cards out. You common sense when you send card. You don't need to wrap two common cards in a refrigerator box to make sure they arrive safely. For a couple of cards I put them in a top loader with a piece of Scotch tape across the top so they don't get out. I also fold a small tab on the edge of the tape so that it peels off easily.
Many people have different methods, which is great. Just make sure when you're getting cards ready to go that they're secure and stiff. If the trade involves some more valuable cards, bubble mailers and insurance is recommended. - tip from www.tradercracks.com
