The Whiteboard O+C system is an innovative and versatile solution designed specifically for effective presentations and collaborative working environments. This mobile whiteboard is characterized by its practical construction on castors, which enables easy movement and flexible use in different rooms. One side of the whiteboard is magnetic and is ideal for writing, drawing and presenting content with dry-erase markers. This feature allows users to visualize, explain and share their ideas in real time. The smooth surface makes it easy to write and erase, enabling a dynamic exchange of information during meetings or training sessions. On the other side of the board is a pinboard, which makes it possible to pin documents, notes or other important information. This creates an extra dimension for the presentation of materials and promotes structured organization of content. The pinboard side is particularly useful when it comes to keeping track of physical documents or reminders. The mobility of the Whiteboard O+C system on castors allows users to move the board effortlessly from one room to another to cover different areas of use. Whether in meeting rooms, classrooms, offices or workshops - the flexible design allows for quick adaptation to different requirements and situations.
