(sorry i dont have any cake at home)
This simple card kit gives you the opportunity to celebrate someone's birthday in a simple way, is it an emergency?
this will save you from that situation if you forget someone's birthday,
just have it in your wallet (credit card size) and put it in something like a cake or snack or maybe pizza.
No printing support is required.
You can make it different colors according to your wishes with a little more effort.
