Rectangular neodymium magnets with flat faces and square edges, for builds where a round disc will not sit right. The flat sides make them easy to align and seat into square recesses, and the larger blocks deliver a strong, broad holding surface.
These come in sizes from 2mm up to 25mm, in a range of thicknesses. Smaller blocks suit miniatures and small joins; the larger blocks work for terrain, display mounts, and heavier holds.
Each listing shows exact dimensions and pull force. Check the sizing chart below to find the block that matches your project.
