Descrição
As a teacher I use chalkboards on a daily basis. While they are very useful the biggest downside is having to use chalk. Most of the time, there is no chalk left in the classrooms, or it got wet. When you decide to bring your own, it crumbles easily and makes a huge mess. While there are chalk pens available, their design is usually boring and they are slow to use. So I designed my own during a free period.
