Can this be used on chalk board with traditional chalk?

There is a small suction cup that is used to attach the tool to the white board. I am not sure it would attach to a regular blackboard. Also the hole where the marker goes is not big enough for a regular piece of chalk.

Can it be used on a dry erase board?

Yes. This can definately be used on a dry erase board!

I have dry erase paint on my dry wall. Will the suction cup stick on it?

As long as a suction cup will stick to it this will do fine.

I purchased this to be able to make circles on a whiteboard. I got so I could specifically draw out the orbits of the planets in our solar system. I was able to do this quickly and easily and maintain a relative distance between all of the orbits. My only complaint regarding this item would be that the suction cup adheres to the whiteboard too well! When trying to remove it from the whiteboard I almost pulled the board off of the wall. (The whiteboard, while attached to the wall, wasn’t “fixed” to the wall.)

Esta excelente, ayuda mucho a la hora de hacer figuras geométricas. El material es resistente, no es del plástico rígido qué se puede romper en cualquier momento al ejercer presión. Se raya rápido, pero eso no afecta en su uso. Estoy muy feliz con la compra.

Half of the compass was delivered. Missing the radius holes (red piece in the middle). I’m returning it.
