Um, okay.  {Insert awkward contemplative silence here}  They're 4" x 6" prank postcards.  So, you'll want to send them to people as a joke.Remember, these are postcards; which mean no envelopes or return addresses and you remain COMPLETELY anonymous unless you specify otherwise when ordering.We'll hand address these little beauties and send them to whomever you choose with the lucky recipient's name printed on the front for everyone see.  This is what makes them awesome!As much fun as these postcards are to send and receive, we're not out to wreck people's lives.  For this reason we have printed a QR code and an inconspicuous web address on the back where recipients can go "to learn more."  So, rest easy!  Most likely, your man isn't actually donating sperm to a fertility clinic.
