While Think Geek’s claims of the Messograf Caliper Pen being “the best looking pen on the block” might be taken as a slight exaggeration, it must be said that it is a pretty good looking pen. It also has some cool little measuring functions built into it – first and foremost is the Venier caliper, but the tire depth and screw thread measurement functions are pretty cool too.
- Made in Germany and is the best looking pen on the block
- It’s a pen, it’s a Vernier caliper, it’ll check your tire tread!
- Retractable ballpoint pen to mark down your measurements
- 4? exterior Vernier caliper (0.1mm metric and 1/16 inch scale)
- Metric screw thread scale and tire tread depth scale, too!
