'Breast Friends' Card

We all have that friend that when you get together you can't help acting like a right pair of tits.  A fun and lighthearted card for a great friend.
The words read:
"Breast Friends Forever
(because when we're together we're always a right pair of tits)"
 
Each card is A6 and comes with a recycled brown envelope. As I am trying to cut down on my use if plastic, the cards will either come in a cornstarch compostable wrapper or, even better, packaged naked.
