Can these be shipped in the mail in a greeting card?

Yes, you can definitely send Flutterflyers as part of a greeting card! It's an extra fun way to surprise your loved ones. To ensure they reach their destination in perfect condition, we recommend adding the "Non-Machinable" postage for an additional 50 cents. This way, USPS will take extra care and handle your Flutterflyers by hand instead of using machines. It's worth the extra investment to make sure your fluttering friend arrives safe and sound, ready to surprise and delight!
