This Steam Piston Pen is a revolutionary writing instrument that uses steam power to create a unique, smoky writing experience.
To use, simply place a small container of water and a pinch of steam-generating powder in the pen's tank. The pen will then produce a continuous stream of smoke, allowing you to write with style and flair.
But be warned: the steam can get hot, so be careful not to burn yourself.
