50 4.5 millimeter by 2.2 millimeter flush-fit base magnets N52 Neodymium Magnets. Coating: NiCuNi
How to Use Flush Fit Base Magnets
Use these to mount your miniatures to magnetic movement trays, cookie sheets, Magna Racks, Table War case, etc.
Use the following size for each base. The "Thin" size is 2mm thick, so it won't hold as well on taller bases like 40mm bases. Thick magnets are 2.6mm thick, which won't sit flush under a 25mm base. You can always use 2 of the thinner magnets on a 40mm base to get a stronger hold rather than buying a whole pack just for 1 or 2 character models.
25mm & 28mm Medium (4.5x2.2mm)
32mm-100m Round & 60mm - 120mm Oval Bases, use the Thick Flush Fits (2.6mm thick). Mediums are better for delicate models, Large Thicks are better for heavier and sturdier models.
160mm Round & 170mm Oval, Large Thin (6x2mm) Between 4-6 depending on how heavy the model is.
6x2.2mm magnets have been replaced by the Large Thick 6x2.6mm magnets.
Rare Earth magnets are the strongest magnets in the world. These magnets have pull several times their weight.
