This brass ballpoint pen is compact for easy carrying and extends for writing, and also boasts a depth in texture that solid brass acquires over time and use, complemented with a high-quality finish created by skilled Japanese craftsmen. The top of the pen has a ring for attaching a hook or string, so you can clip it to your bag as a key holder or customize it using beads and other items. The ring can also be removed for a clip-free pen if you prefer. The pen uses international standard cartridges, available in black and blue-black.
