~ A wearable pen comprises a pen and a neck cord. The pen comprises a pen body and a ferromagnetic element. The neck cord comprises a loop-shaped cord, a permanent magnet, and a means for securely mounting the permanent magnet to the loop-shaped cord. The pen is capable of attaching to the neck cord by the magnetic attraction force in a single-hand operation when a user places the ferromagnetic element of the pen in proximity to the permanent magnet of the neck cord. The ferromagnetic element of the pen is capable of detaching from the permanent magnet of the neck cord in a single-hand operation when a user applies a force greater than the magnetic attraction force between the ferromagnetic element of the pen and the permanent magnet of the neck cord. This invention relates to pens, and the principal use of the invention is for operating a pen with a single hand.
