The 01 is world’s first dimensioning instrument. Carved in aluminum, and contained within a pen, 01 is both a serious writing instrument and a to-go tape measure for 3-dimensional space. Using one of the complementary apps, the 01 rolls to capture the dimensions or 3D curves of any object, then logs, converts and shares them through your smartphone. You can even download them to key CAD software and export them, with the use of an optional subscription service (sold separately).

Measure space for furniture before you go couch shopping, put up pictures, set up grid for posters, or get the length of materials needed for a building project. Quickly log H*W*D in almost any format, measure and log complex contours, measure the height of your kids, use a scale and read drawings, or anything else you can think of. And when the project's done, instantly snap a pic, complete with the dimensions, and share it with your friends or coworkers.

Beginning with the pen, 01 is made with the highest quality, German-made ink cartridges and twist mechanisms, and from-scratch pencil mechanisms, and then the technology was crafted around them. This means that it feels perfectly balanced in your hand, and the weight, feel and roll are just right, making 01 a must-have in your bag, purse or pocket.
