The Inart K-Line 5mm 100x140cm White Board (120010542/10581) is the largest format available in 5mm thickness, composed of polyethylene foam pressed between two sheets of white cardboard, moisture-repellent and with excellent rigidity despite its low weight. The large 100x140cm format is suitable for large-scale models, complete exhibition panels or poster supports that need to cover a wide area without joints or seams. The smooth white finish serves as a neutral base for both technical drawing and for pasting photographs, posters or fine finishing work. Despite its size, the material is easily cut using a craft knife and metal ruler and folds without tearing in controlled creases, making it suitable for architecture and design students working on large-scale projects on a single support.
