"It was a business card that couldn't be mistaken by any means. (Omitted) It was just a piece of paper that was unmistakable." (From the crime of Mr. S. Karma, Part 1 of "The Wall" by Kobo Abe)
However, it seems that business cards do not necessarily have to be "paper."
I introduced a business card that grate cheese before, but a company called Meat Cards manufactures and sells business cards made of beef jerky. Of course, you can eat it. The US media Foodbeast reports.
According to the media, beef jerky business cards are business cards in which the name and contact information are engraved on dried meat (beef jerky) using a laser. The expiration date is one year.
I was wondering what kind of people would buy it, but it seems that the company's website has actually received inquiries from people who sell food for restaurants and hotels asking them to order beef jerky business cards. This unique and impactful business card may have a good reputation among businessmen working for food companies.
If you think to the person who received your business card, "I don't think I'll be working with this person anymore ...", you can eat it as a beer snack tonight. What an eco-friendly beef jerky business card. However, again, the best-by date is one year.
