Can you use a dry erase on a chalkboard?
Although dry erase markers, permanent markers, and other inks will not damage the CeramicSteel Blackboard, they are not recommended; for clarity, these tools cannot provide sufficient contrast with the dark surface of the Blackboard.
Smart Blackboard is an intelligent interactive teaching device that integrates capacitive touch, LCD display, computer host, multimedia video booth and traditional handwriting blackboard functions in one. It covers touch interaction, Multi-media Equipment teaching and chalk writing, and seamlessly integrates the traditional teaching blackboard with the perceptible Interactive Blackboard. The front is shown as a flat ordinary blackboard composed of three pieces spliced together, on which ordinary chalk can be used to write smoothly. The whole machine has a one-key multimedia function: when the power is turned on, the middle capacitive touch screen displays a picture, which can be touched and interacted, and when it is turned off, the display picture is black, and it is displayed as an ordinary blackboard, and you can write on it.
