You never know when you’ll need to measure something, and let’s face, we need to do this more often than we believe. With the ShiKai Tseng Ruler Pen, you’ll never be without a measuring tool again.

Considering that most people carry a pen with them at all times (it’s one of the day-to-day staples that we don’t even think twice about, it’s simply always in a pocket), having the ShiKai Tseng Ruler Pen will ensure that you are always well equipped.
