Not every space pen has to look like some futuristic writing instrument. The M4B blends the benefits of a space pen—they can write upside down, from any angle, under water, over grease, and at extreme temperatures—with the style of a sleek and simple writing instrument. The cap activation extends and retracts the point, and the M4B allows you to write three times longer than the average pen. Made in the USA with recyclable parts.
