The Inart K-Line 5mm 70x100cm White Board (120010529/120010509) expands the 5mm white format to a larger working area, suitable for more voluminous models, larger exhibition panels, or projects requiring more space than the equivalent 50x70cm format. The white finish remains the most versatile option in the range, serving both as a neutral base for technical drawing and as a support for pasting photographs, posters, or painted pieces. The 5mm thickness ensures greater flexural rigidity than the 3mm versions in the same format, keeping the board flatter when displayed vertically or used as a presentation panel without additional support. It is ideal for architecture and design students who need more working space without sacrificing the rigidity that the 5mm thickness provides compared to thinner boards.
