How long is it? / Digital ballpen

How long is it?
How long is it?

The measuring tape and the measuring bar we use all the time. But there's got to be another brand new way to measure. What is this pen for by the way? A LCD screen on the Pen!
Eureka! How come this idea has not come out yet?
The combination of a pen and a ruler.
Whenever drawing the line with the pen, the measure coming out automatically. No more pen and the ruler needed separately. You have a pen? you are going to be able to measure anything so simple. Whether it is a straight line or a curved line.
