We always feel anxious about the different paintbushes mixed up all around when we draw a picture on the table. Besides, it is a annoying problem for us to bring many pens when we have a outdoor drawing activity. The design of this technical pen is based on lego block's way, attaching one type of the pen to the other. The simplest geometric form is used as the basic element. Not only makes our study envoriment more clean, but also makes our life more convenient and funny.
