Kaarthouder - Carbon Fiber Business Card Holder
Removing a card from The Kaarthouder™ business card case

The Kaarthouder™ is a one piece business card holder designed to create that "wow" factor when you pull it out of your pocket. The 100% carbon fiber construction case has a natural curve, so it fits more comfortably in your pocket (similar to the design of a flask). It can hold up to 12 thicker than average business cards or more if you are using standard or thinner business cards. The natural curve of the case has a second function, which is to hold the cards securely when there are a lot of cards. When carrying fewer cards or even a single card you can give the card a slight bend and insert it in the case opposite the curvature of The Kaarthouder™ to ensure it stays in place until needed.

Fits standard North American sized business cards 3.5in x 2in (89mm × 51 mm) and standard UK business cards 3.35in × 2.17in (85 × 55 mm). The absolute biggest business card this case can hold is 3.5in x 2.17in (89mm x 55mm).

Producing high quality carbon fiber composites takes a lot of skill and experience and the proper design. You will be impressed with the precision and workmanship on this technical work of art!



Carbon fiber consists of extremely thin fibers ranging from 0.005 – 0.010 mm diameter. To form the yarn thousands of carbon fibers are twisted together.

Carbon fiber has many different weave patterns and when combined with a resin it can be molded to form a high strength-to-weight ratio material.

Carbon fiber is very lightweight and has considerably lower density than steel, making it ideal for aerospace, military, and motorsports racing.
