- 【300 Pack, 4×2mm Magnets — Keep Your Desktop Tidy Without You Even Noticing】—— With 300 pieces of 4×2 mm neodymium tiny magnets, you get a desktop solution so tiny it is practically invisible — yet these mini magnets can quietly transform your workspace. Tuck one inside a pencil holder, and pens and paperclips will snap into place the moment you set them down. Stick another to the edge of your desk; wrap your earbuds or charging cable around it, and they'll stay put instead of slipping off and tangling into a knot.
- 【Safe & Gentle Holding Power】 —— Our neodymium magnet provide just the right amount of attraction for everyday use – strong enough to hold photos, memos, and lightweight items, yet gentle enough to avoid pinching fingers, damaging delicate surfaces, or interfering with nearby electronics . A safer choice for home, classroom, and hobby applications.
- 【Superior Coating + Hydrophobic Surface】—— Our rare earth magnets feature a nickel‑copper‑nickel coating that delivers 5–8× better corrosion resistance than single‑layer plating, passes 48‑hour salt spray testing and withstands up to 390°C, while their hydrophobic surface (110° water contact angle) actively repels moisture to prevent rust and degradation in demanding environments.
- 【Precision Hobby Magnets】—— Our mini magnets (4×2mm & 5×2mm) are purpose-built for precision hobby work – seamlessly embedding into miniature figures, model bases, and papercraft projects. Their tiny footprint allows discreet placement while still providing dependable hold for lightweight parts, making them a favorite among scale modelers, miniaturists, and scrapbook enthusiasts.
- 【Proper Handling & Storage — Safety First】Important Safety Instructions:These disc magnets are extremely strong. Keep them at least 12 inches apart until ready to join to avoid sudden impact that may cause shattering. Keep away from: Children under 14, pacemakers, credit cards, mechanical watches, and electronic devices (minimum 12-inch distance). If circle magnets cracks or chips, stop using immediately. Dispose of safely by wrapping in thick cardboard or plastic — do not handle fragments directly.
