Teaching Writing Board is developed and produced by Qtenboard, Ltd. It features a double-layer structure—with a fixed writing board on the inner layer and a sliding writing board on the outer layer—that enables free opening and closing to protect the built-in all-in-one machine and support the central installation of interactive teaching whiteboards. The product adheres to strict standards for material safety, structural stability, and environmental protection: its matte board surface eliminates glare to reduce students’ visual fatigue, formaldehyde emissions are ultra-low, and there are no sharp edges, making it a practical and safe choice for smart education scenarios.

Q: Can the board surface be used with water-based pens?
A: Only the green board surface supports water-based pens. For other colors, use soft dust-free chalk. When using water-based pens, match them with a dedicated eraser to avoid residual marks.
Q: What if the sliding board’s lock key is lost?
A: The lock uses universal keys. Contact the manufacturer to request a replacement—no need to change the entire lock.
Q: Can large teaching tools be stored in the multi-purpose slot?
A: No. The slot (width ≥30mm) is only for small items like pens or pointers. Large tools may jam the sliding system; store them separately.
