50pcs 3mm x 4mm (Approximately 1/8" x 5/32") Cylinder Magnets

A short, stubby cylinder that packs a strong hold into a compact 3mm hole. Think of it as the deeper, grabbier cousin of the 3mm discs. Great for weapon swaps, arms, backpacks, and joints that need a firmer bite than a thin disc can give, plus craft closures, box lids, and latches that have to stay put.

At 3mm x 4mm they sit deeper than a disc without needing the long bore of our 11.5mm and 14mm cylinders, so they're an easy upgrade when a disc just isn't holding. Seat them in a snug 3mm hole and they grip hard end to end.

N52 neodymium rare earth magnets, so they pull several times their own weight. Good for anything you'd normally use Velcro, brass fasteners, hinges, or pins for.

WARNING: More brittle than glass, so don't let them slam together or drop them on a hard floor; they'll crack. Keep them away from anyone who might swallow them, kids or pets included, since magnets that get swallowed can pinch through the intestines and cause serious harm.
