This handy little pen is an incredibly tough and capable compact machined rollerball clicker-style pen. The 1.6-ounce, 5-inch body is constructed in the U.S. from a lightweight 6061 aluminum with a tumbled finish and the durable all-metal clicker was manufactured by Schmidt, in Germany. This pen also comes pre-loaded with a Schmidt P8126 cartridge, but can accept any Parker ballpoint compatible refill. If you need a long-lasting pen that wont let you down, the EDK will do the trick.
