Did you just meet someone awesome, but you are super sad about where you work and so you don't want to just give them your business card? That happens to me probably fifteen or sixteen times a day. These are calling cards are for that occassion. These calling cards are for that occasion. They are blank on the back so you can write in your email address or phone number or website or do one of those lipstick kiss things. They are pretty much guaranteed to work really well. That is why there are 10 cards per pack. That is all you will need I bet.
