Rare Earth Magnet Disc 0.4x1.5mm N42 Neodymium

Rare Earth Magnet Disc 0.4x1.5mm N42 Neodymium for Detail Work

Small magnets that fail under load are every maker's headache. This 0.4 x 1.5mm N42 neodymium rare earth magnet disc is sized for delicate work yet packs the holding strength of magnets twice its volume — finally, a tiny disc that pulls its weight.

The struggle with miniature magnetic builds is real — generic crafting magnets either snap when you press-fit them or simply lose strength after a few wash cycles. Precision N42 neodymium discs solve both problems. The slightly larger 1.5mm diameter gives broader surface contact than ultra-mini discs while remaining nearly invisible inside cardstock, leather, fabric, or 3D-printed parts. Use them in costume closures, magnetic dice towers, miniature dioramas, custom jewelry, lapel pin backs, escape room props, and gemstone identification kits. The nickel-copper-nickel triple plating keeps these discs corrosion-free and looking sharp for years.

Key Features

• N42 grade neodymium delivers strong, lasting magnetic pull
• Triple-plated nickel-copper-nickel finish prevents rust and chipping
