A polyhedron magnet device for attaching to magnetically attractive surfaces and holding items. The device comprises a plurality of sidewalls extending in a longitudinal direction along the surface of the device, partitions, and end walls, which are placed perpendicularly to sidewalls to form one or more magnet holding chambers and separation chambers. Magnets are placed into magnet holding chambers. The separation chamber maintains magnetic interaction between magnets in separated magnet holding chambers. Advertising banners are connected to sidewalls and end walls by printing, adhesive substance, and magnetically attracting. The magnets create the magnetic attraction.
