The Inart K-Line 3mm A4 White Board (120010352) is the most compact format in the range for this thickness, practical for small models, school projects, and presentations that don't require a large surface area. At 3mm thick, it combines lightness with sufficient rigidity to remain flat without additional support, easily cutting with a craft knife and metal ruler in clean, straight lines, even for beginners. Being already A4 size, it's easy to store in drawing folders, binders, or school bags without needing to fold or cut the board to fit the available space. It's suitable for primary and secondary school students and for art or technology school projects that require a lightweight, rigid, and easily cut small-format support.
