I carry this every single day, everywhere I go, the Zebra F-301 Compact Ballpoint Pen.

The Zebra F-301 Compact Pen has the following great features:
- Collapses to half the size of a regular pen
- Small size fits in the front pocket of jeans or slacks
- The pen is covered when collapsed; it keeps ink off your clothes
- Quality stainless steel construction
- The hole for a small keychain ring on the top
- An everyday carry (EDC) masterpiece
Using the Zebra F-301 Compact Pen
To use, pull the cap from the pen’s main body, then put the cap on the other end to create a full-sized pen. Having a pen wherever you go is important, and this makes it easy. Great for “everyday carry” or EDC. The Zebra F-301 converts from pocket-size to full-size! Highly recommended.

Fine point (0.7 mm), black ink. Pack of two pens; nice for the price. UPC number is 045888274129; Zebra Pen SKU is 27410PROD. Find more at Zebra USA.
