Chalk Dust Cleaner / Vacuum cleaner

Chalk Dust Cleaner

I remember when I was a student, one of the things that bothered me the most was
cleaning the messy, dusty chalk tray. This tray collects the chalk dust but because of
its design, I not only stained my hands and clothing, but also inhaled the dust as I
cleaned the tray. This could potentially cause medical problems for regular users.

With this in mind I have developed a simple, new and inexpensive solution.
The brand new design “Chalk Dust Cleaner”, everyone can clean the chalk tray
easier and efficiently, and most important, keep one's hands free from the dust.
