This ballpoint is made in Tokyo by the Travelers Company. The barrel of the pen itself sits in a brass cap with a handy pocket clip. When capped the pen is 9.5 cm. Once the pen is in use (with the cap becoming the barrel) it measures 13.5cm. The brass cap will develop a natural patina with continued use, or can be polished to retain it's shine.
You can easily carry it around anytime, anywhere by roughly inserting it into a pen holder or throwing it into your pocket. It looks like a tough and easy-to-use craftsman's tool that you don't really care about small scratches, but rather it seems to be a taste. By using it every day, you will deepen your attachment and become a companion to your life journey.
