The Inart K-Line 10mm 70x100cm White Board (120011014) is the thickest version in the K-Line range, composed of polystyrene foam pressed between two sheets of cardboard, which guarantees high rigidity even in large-format boards like this one. Its 10mm thickness makes it especially resistant to bending, making it the ideal choice for architectural models, exhibition panels, and supports that need to remain perfectly flat without additional support. Despite its thickness, the material is easily cut using a craft knife and a metal ruler, maintaining clean and straight cuts. The large 70x100cm format is suitable for larger-scale projects, such as complete models or exhibition panels, and is ideal for architecture, design, and fine arts students working with three-dimensional models.
