It is a ballpoint pen that integrates with a brass holder made in Japan at a press factory.
When not in use, the pen can be placed inside the main body for compact transportation. Top includes a ring for hook or string attachment. You can also use it without a clip by removing the ring part. Simply clip the clip onto the leather cover, remove the clip and toss it in your pocket, or use it as a companion for your life journey.
Solid brass glows gold at the beginning of use, but with continued use, the surface will oxidize and turn into a deep, tasty hue. Refills are also available, so you can use them for a long time and enjoy the change.
