4462/6031 – 2010-25 Butterflies, set of 9 stamps

Have you ever sent a card or invitation that was a little too unique for standard postage? Non-Machinable stamps are designed for just that – they cover the special handling for mail pieces that can’t go through automated sorting machines. Whether it’s a square envelope, a handmade greeting card, or a letter with an unusual shape, these stamps ensure your special mail reaches its destination safely.

Non-Machinable stamps were first introduced in 2010, and each one has featured detailed photography of a butterfly – symbolizing the special care needed for unique mail pieces.

When you use a Non-Machinable stamp, you’re covering the extra effort of a postal worker who must manually process your mail piece – ensuring it gets the attention it deserves.

With this special collectors set you’ll get all nine non-machinables in one easy order!  Here’s what you’ll get:
