Collection: Cosplay & Prop Magnets

Cosplay needs magnets that hold heavy foam and 3D-printed armor without snagging fabric or showing on the surface. 12x3 and 20x5 countersunk rings take an M3 or M5 flat-head screw and sit flush in EVA foam or PLA. The chrome 1/4 inch countersunk hides best on visible mounts (jewelry-style closures and decorative panels).

Rule of thumb: pick the size that pulls double the part weight. Foam pauldron with battery pack inside? 20x5 minimum.
