Three in one / Drawing tools

Three in one
Three in one

Students and designers need to draw pictures at many times. Thus they have many drawing instruments, which are inconvenient to bring alone. Now, with the existence of the three-in-one drawing tool, we can combine the three tools, namely, rulers, compasses and protractor into one. Additionally, gray scale sensor, infrared electronic distance meter and high-resolution monitor are used to create enjoyment for users.
