Teacher's protector / Eraser

Teacher's protector
Teacher's protector

During classes, the blackboard is always full of points written by teachers. We have to raise our hands high to erase the blackboard back and forth many times. In the process, not only students but teachers also breathes in a lot of chalk.
The idea of the design is having special material to adsorb chalk, which is on the rod across the blackboard. As you move the rod, you can make the blackboard clean. In addition, the bottom is the transparent dust-collecting box. If you want to clean a small part of it, just take the eraser out of the rod. This device can improve the efficiency; moreover, teachers and students no longer suffer from chalk.
