Story
As you've likely gathered, Stübby (pronounced shtoo-bee, or stew-bee, or stuh-bee, or however you like) is a pen that counter-intuitively gets longer in the direction opposite from which it's pulled. Wow. It was invented by Sherwood Forlee in 2021 in West LA, but has its origins in 2003 in Queens, NY. Yes… it took a long time and a long distance to implement, but some good ideas sometimes require some good inspiration :P
While seemingly magical, the mechanisms involved that allow for the transformation from closed to open and vice versa are straightforward and easy to understand. A cursory glance at the individual parts should be enough to inform you of the construction, mechanical principles, and material assignments. If not, you should buy Stübby and simply indulge in the magic of it.
Stübby features a metallic- or ceramic-coated aluminum body with high-wear polymer internals (think: your favorite double-walled or porcelain coffee mug, but the pen you use while you sip from it and solve Sudoku puzzles). It locks open or closed because of magnets, which are closely tuned to standard writing pressures.
The art of hand-writing is still aliving and thriving. And—as with any art form—the more varied the palette of instruments, the more profound the composition. Tug on Stübby and let the coda of your masterpiece gush forth!
