Mr. ZIP Thinks Outside of the Box!

Think Outside of the Box! Send your partner each one item that is not square or rectangular. The item should still be flat mail (not a package or 3D like a rubber ball), but it should be round or irregular - anything but square. In the USA, you will have to add the 21-cent non-machinable charge. Do not put your item into an envelope, unless you are sending an envelope that is not square. Some ideas include a triangle postalette or a round postcard or a big Shrinky-Dink or a snowflake - anything you can imagine. It does NOT have to be paper. This is not a penpal or an art swap, so keep it fairly simple - no need to get elaborate or spend more than a tiny bit of money. This is Sender's Choice, so you can start preparing your items right away. Your challenge is to "think outside of the box"!!
