This five round clip, aka five gunmetal plated high power rare earth (neodymium) magnets can be used for a wide variety of applications, such as multi-color customized pens, excellent fridge magnets, business card holder and so much much more.

Every POLAR Pen Version 2.0 comes with two spare magnets but for certain applications or extreme uses this may not be enough. We always recommend serious tinkerers to acquire extra magnets as they can fracture if repeatedly snapped together from far distances or dropped onto hard surfaces.
