Rare Earth Magnet Disc 0.3x1mm N42 Neodymium for Precision Work
Need a magnet so small it can hide between two business cards but still hold its own? This 0.3 x 1mm N42 neodymium rare earth magnet disc is engineered for micro-scale projects where every fraction of a millimetre matters and weak magnets are not an option.
Trying to glue magnets onto miniature paper craft, watch repairs, or fine jewelry usually ends in frustration — they're either too thick, too weak, or too brittle. This precision-machined N42 grade disc solves all three problems. The thin profile slides under fabric, paper, or laminate without showing, while the high-grade neodymium core delivers a surprising clamp force for its size. The protective nickel coating shrugs off oxidation, so the magnet holds strength for years instead of months. Engineers, hobbyists, dentists, escape-room builders, and miniature painters all reach for sub-millimetre discs like this — and now you can stock up without paying boutique prices.
