The days of hiding your mess of a toolbox under the sink are over. This award-winning tool pen puts everything you need in the palm of your hand. Sixteen individual bits provide every possible permutation of tool. The pen can hold up to six bits at a time, each one stacking neatly on top of the other, while a display window showcases each bit's individual marking so you always know the order. A magnetic cap prevents the pen from poking you while you hold it in your pocket, and makes this tool as travel-friendly as it is convenient.
