Japan Maritime Self-Defense Force Military Souvenir When you turn the ship's body, the pen tip appears from the front! Submarine Ballpoint Pen Soryu - Submarine: SORAYU - Color: Black When you turn the ship's body around, the pen tip comes out from the front. I have kept it in the box without using it. (I have not confirmed whether it can be used as a ballpoint pen. Please consider it as a display item only). Since it is a used item, please refrain from purchasing if you are sensitive to such things.
