ATARI 2600 CARTRIDGES MAKE EXCELLENT BUSINESS CARD HOLDERS
Violet Tchalakov and Mike James (aka PRINTandGRAIN) have this incredibly clever business card holder for sale over at their Etsy Store. Not only is the design clever but they can take it one step further with custom labels for your card holder.
The custom part of this item has you pick your favorite 2600 game which they can customize the titles as well as the top facing label. This is such an brilliant repurposing of classic video game equipment that it makes it worth the $75 asking price for something that unique.
