This was my thinking, ive (its you, im just speaking in third person) have  just arrived at Kiosk and while thanking the gods for such a find, ive (or rather you) have  decided to buy a gift and send it straight to the recipient but wouldn't that experience be elevated if I (you) could send an actual, real life, proper, funny but also eco card. Oh my the universe has answered your thinking. 
Add a hand printed card to your order, write your message in the notes section of the checkout and ill use my best pen (Artliner) and best writing to add the message.

or you actually just want a card or two for the kitchen drawer incase of emergencies, ill send them to you untouched and ready for your prose and best Victorian cursive.
