The kiss(es) can be placed where you want on the card, and I'll leave enough space so a message can be added (by me or yourself).
I use paper of fine quality and may add some perfume if you wish (for free).
It's an original way to say to a precious person that you like him/her.
You may also use it to send an anonymous love letter...
... or to make your friends believe you have a girlfriend ;)
A card kissed 1-3 times with the lipstick color you want and sent wherever you want.
