Meat Cards are 100% business card, 0% bulls***.
The Meat Card is a piece of 100% beef jerky that is emblazoned with your contact information using a 150 watt carbon dioxide laser. They say it on their site better than I ever could:
We start with 100% beef jerky, and SEAR your contact information into it with a 150 WATT CO2 LASER. Screw die-cutting. Forget about foil, popups, or UV spot lamination. THESE business cards have two ingredients: MEAT AND LASERS. Unlike other business cards, MEAT CARDS will retain value after the econopocalypse. Hoard and barter your calorie-rich, life-sustaining cards.
