The Colorarte 60º/60cm Whiteboard Set Square with Magnet RCQ04 is a large-format geometric tool, 60cm long, designed for drawing 60-degree angles directly on whiteboards or slates. The built-in magnet allows it to be attached to the board without needing to hold it, facilitating teacher demonstrations and ensuring more precise and stable lines during class. Its generous size makes this set square easily visible even to students sitting at the back of the room, making geometry explanations clearer and more effective. It is an indispensable tool for mathematics and technical drawing teachers.
