Are you working at Schools? Are you a teacher or tuition centre teacher or parents? Why don't you recommend your principal to change the chalk or marker for health of the students and teachers and clean the classroom?
Here are the Bio Chalk and Magic Marker, which are made for Teacher and Students' health. No dust or powder droping down or flying in the air or No toxic smell coming out of the marker while you write down on the board in the classroom.
Sometimes you may feel any headache due to a toxic smell coming out of the normal marker because they have an alcohol inside while writing down on the whiteboard.
But no need to worry about such headache while writing down on the board because no toxic smell comes out of the Magic Marker.
Sometimes you may forget to close the cap of marker after using them. And then, it's not easy to write down again because it was already dry. But no need to worry about that because Magic Marker will not be dry even though you forget to close the cap after using them. You can keep using them again as usual.
P.S) "Pls Call Seller directly at 9237-9928 regarding the change of the chalkboard or whiteboard sheet".

It is a functional product that can change the existing board to the pro-environmental board at once by attaching it to the existing board.
