The Bullet's timeless styling has been the topic of many art books and magazines and continues to be one of the world's most popular pens. The technology behind this fabulous pen is renowned - developed at huge expense by NASA for the US space programme, it writes at any angle, pretty much any temperature, and even underwater! In fact, it flawlessly performs in some of the harshest environments so far explored by man. Precision stainless steel tungsten carbide ball points and a fully pressurised ink cartridge, enable this design classic to write longer, cleaner and more consistently than almost any other pen. This lovely slim pen fits into the smallest of bags, and is definitely pocketable!
