The Dahle Mega Magnet, 80mm in size and yellow in color, is a large, circular magnet with a strong holding force, used to attach posters, maps, and heavier documents to magnetic boards or metal surfaces where a conventional magnet would be insufficient. The 80mm size is one of the largest in the Mega Magnet range, ensuring a particularly firm hold. The yellow color provides good visibility from a distance, making it useful for marking important notices. It is a suitable accessory for meeting rooms, offices, and exhibition spaces that handle heavier materials.
