• 【350 Pack, 6 Sizes — Tiny Tools for Detailed Hands】Built for the maker who sweats the small stuff. This set leads with 150 pieces of 3×1 mm small round magnets—ultra-thin, ultra-light, and perfect for slipping into 3D-printed slots, paper crafts, or delicate model work. You'll also find 4×2, 5×2, and 6×2 mm magnets in smaller counts for when a project needs just a little extra hold. A handful of 8×2 and 10×2 mm pieces round out the kit for the occasional fridge pin-up or cabinet catch. If small magnets for craft precision is what you're after, this is your set.
• 【Neodymium Magnets — Everyday Strength, Simple Reliability】Crafted from rare-earth NdFeB material, these magnets deliver practical holding power for everyday tasks. One 10×2mm small round magnets can grip about 6-7 sheets of A4 paper — just right for lightweight jobs around the home. Whether you need small magnets for craft projects, fridge organization, or simple closures, they offer dependable performance. Triple-layer Ni-Cu-Ni plating resists rust, even in humid kitchens and bathrooms.
• 【Thickness Matters — More Than Just Diameter】Same diameter, different story. A 10×3mm magnet holds nearly twice as much as a 10×2mm of the same grade. Working with paper, photos, or lightweight notes? 2mm thickness is plenty. Hanging something heavier or dealing with slightly uneven surfaces? Step up to 3mm or more. When in doubt, go thicker—you can always use less force, but you can't add strength that is not there.
• 【Application Guide — Picking the Right Size】Going invisible? Stick with 1.5–2mm. These mini magnets hide in models, jewelry, and fine crafts. Working with 3D prints? 3–5mm fits standard slots and modular builds. Everyday fridge duty? 6–10mm handles photos, notes, whiteboards—classic refrigerator magnets. Need real power? 10–12mm steps up for tools, shelves, and garage tasks. From mini magnets to refrigerator magnets, there is a size that fits.
• 【Works on Multiple Surfaces — Fridge, Whiteboard, Metal, and More】These strong magnets grip securely to any ferromagnetic surface: refrigerators, whiteboards, metal cabinets, tool chests, steel doors, filing cabinets, and workshop pegboards. For non-magnetic surfaces like wood, glass, or plastic, pair them with adhesive backing or a steel strike plate. The smooth nickel finish glides without scratching—perfect for displaying photos, organizing notes, holding tools, or custom setups in your kitchen, office, garage, or classroom.
• 【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.
