This is an extremely rare item. You likely won't find it for sale anywhere else. It's from the Pilot fountain pen era. This is a pen that can listen to the radio, which Pilot sold for only three years, over 40 years ago. The refills are generic and can be replaced. The included earphones' functionality hasn't been confirmed. Also, the earphone cushions have deteriorated, so please replace them. The ballpoint pen itself can be clicked, and I've confirmed that it can receive radio broadcasts. I will include one button battery, imported from overseas. Please note that the box has some scratches. Contents: Instruction manual, ballpoint pen body, button battery, earphones
