These map pins are designed for marking key locations, routes, or points of interest on maps, plans, and notice boards. Each pin features a 4.5mm spherical head made from durable plastic, paired with a hardened steel shaft for reliable penetration into cork surfaces, paper, or foam boards. The pack includes 100 pins, suitable for use in offices, classrooms, or at home for project planning and document organisation. The hardened steel construction ensures that the pins remain straight and functional during regular use.
