The Inart K-Line 5mm A3 White Board (120010527) comes in the standard A3 format, practical for those who work directly from technical drawings or plans in this size without having to cut a larger board to size. The white finish is the most versatile option in the range, serving both as a neutral base for technical drawing and as a support for gluing photographs, posters, or assembled model pieces after cutting. The 5mm thickness guarantees greater flexural rigidity than the 3mm versions in the same A3 format, keeping the board flatter on presentation supports or table displays without warping over time. It is suitable for architecture, design, and fine arts students who regularly work in A3 format and need more rigidity than that offered by thin 3mm boards.
