This is by far the best way to give a birthday card/present...
A birthday card that turns into a shot glass, genius.
The cost about $5, and are available in blue and orange.
Now I've never understood the idea behind cards, ok I understand the idea, but have you seen the prices of cards lately. To anyone wanting to send me a card, or give me a card, I have a better solution, write a nice little blurb on a post-it note, and place it on a $5 bill. Then just hand me the $5 bill, when I spend it, and I will, I'll see your note and read it, and think of you. See, no card needed.
