Just your standard congratulatory card for any occasion that calls for a drink. Hell, you can force this into just about any situation. Kindergarten graduation? Congratulations shot glass cards for everybody. Ok, seriously don't do that. That was a joke. You'll go to jail.
The Bottle Hanger Card
The card features a diecut circle at the top to attach it to all sizes of bottle (even the enormous Absolut bottles if you mean serious business).
