The Inart K-Line 5mm A4 White Board (120010526) is the most compact format in the range at this thickness, practical for small models, school projects, and presentations that don't require a large surface. The white finish is the most versatile option, serving both as a neutral base for technical drawing and as a support for gluing photographs or small cut-out elements without needing an additional frame. The 5mm thickness guarantees greater flexural rigidity than the equivalent 3mm A4 version, keeping the board flatter even without additional support and preventing warping during handling. It is suitable for primary and secondary school students and for school projects in fine arts or technology that require a small but more robust support than thin 3mm boards.
