Q: How resistant is the whiteboard glass to scratches, accidental drops, or active students?
A: The front surface is covered by high-hardness, explosion-proof industrial tempered safety glass. It safely resists scratches from keys, pens, or fingernails, and is structurally optimized to absorb high-frequency impacts without fracturing or damaging the LCD matrix behind it.
