The team of Chinese designers introduced the original concept, which will make handwritten notes more accurate. This compact laser projector that creates a virtual line on a blank sheet of paper. You can adjust the line spacing.
The attached laser unit on the pen cap can easily be rotated 360 degrees or moved up and down according to the users’ convenience. Good thing is that the concept also includes the possibility of increasing or decreasing the distance between the ruled lines to allow different font size or better said, letter size.
