How can a glass writing surface be improved? By making it magnetic as well! Write on the super clear bright white glass surface with normal markers and dry erase just like a traditional whiteboard. Our Magnetic Glassboards are supplied in 4mm safety toughened glass and with wall fittings (either 4 or 6) and either a 300 or 500mm clear glass pen shelf. Soft rounded corners and the magnetic glassboard is guaranteed stain proof for life.
