Made from neodymium iron boron, the set of 100 magnets is intended for hobbyists, technicians, and everyday household tasks where small, reliable magnets are needed. Their smooth finish and corrosion-resistant properties make them easier to handle and longer lasting than ordinary ferrite magnets.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these magnets perform in tight or delicate projects?\u003c\/h3\u003e\n\u003cp\u003eThe 4×3 mm size lets you place magnetic attachment points in confined or visible areas without bulky hardware. Despite their small dimensions, neodymium composition provides noteworthy pull strength for lightweight assemblies and testing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompact footprint: 4 mm diameter keeps attachment discreet.\u003c\/li\u003e\n  \u003cli\u003e3 mm thickness supplies stable contact area for shear and pull forces.\u003c\/li\u003e\n  \u003cli\u003eNeodymium core increases holding power versus ceramic magnets.\u003c\/li\u003e\n  \u003cli\u003ePack of 100 gives consistent, repeatable placement across projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use these magnets with nail tools, 3D prints, or miniatures?\u003c\/h3\u003e\n\u003cp\u003eYes — the magnets are small enough to embed into acrylic nail clippers, model bases, and 3D-printed components. Their low profile makes them suited for concealed installations where appearance and precision matter.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits inside acrylic nail clipper housings for length measurement or magnetic closure.\u003c\/li\u003e\n  \u003cli\u003eEasy to insert into resin or filament prints for detachable parts.\u003c\/li\u003e\n  \u003cli\u003eWorks with miniatures and dioramas for removable elements and poses.\u003c\/li\u003e\n  \u003cli\u003eMultiple magnets allow for balanced magnetic joints or fixtures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat should I know about durability and handling these tiny magnets?\u003c\/h3\u003e\n\u003cp\u003eThese magnets are manufactured to resist demagnetization and oxidation under normal use, and their smooth surfaces reduce scratching on adjoining materials. Because they are very small and strong, follow safe handling practices and keep them away from young children and sensitive electronics.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSurface finish reduces abrasion when installed or removed.\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant design extends usable life in most environments.\u003c\/li\u003e\n  \u003cli\u003eNot recommended for children under 14 due to swallowing and pinching risk.\u003c\/li\u003e\n  \u003cli\u003eStore in a secure container to prevent loss or accidental attraction to metal objects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I choose and place these magnets for best results?\u003c\/h3\u003e\n\u003cp\u003eSelect placement by evaluating gap distance, material thickness, and required holding force; pair magnets when more strength is needed. Test with a single magnet first, then add additional magnets or metal backings to increase holding power or alignment precision.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTest on sample material to confirm pull force before final assembly.\u003c\/li\u003e\n  \u003cli\u003eUse adhesive or press-fit cavities to keep magnets aligned in parts.\u003c\/li\u003e\n  \u003cli\u003eCombine magnets in opposite poles for stronger clamping where necessary.\u003c\/li\u003e\n  \u003cli\u003eAllow small gaps for removable parts to avoid excessive sticking or surface damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? The XEAOHESY 100-pack of 4×3 mm neodymium round magnets is aimed at makers, nail technicians, modelers, educators, and anyone needing compact magnetic solutions. If you build 3D-printed prototypes, craft miniatures, retrofit household fittings, or require tiny magnetic measuring aids for tools, these magnets offer a portable, economical supply for repeated use. Keep in mind age recommendations and safe handling due to their size and strength.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What are the exact dimensions of each magnet?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Each magnet measures 4 mm in diameter and 3 mm thick (approximately 0.157 × 0.118 inches).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are these safe for children?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Not recommended for children under 14 due to small size and swallowing\/pinching hazards.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"XEAOHESY","offers":[{"title":"Default Title","offer_id":51492338663657,"sku":"B0F7K8B2M6","price":55.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/7674\/2633\/files\/xeaohesy-front-packaging_8a08158d-ec89-45f4-ab5b-7ee1a0b03a79.jpg?v=1783360486","url":"https:\/\/cervaaustralia.com\/products\/xeaohesy-4x3mm-neodymium-mini-round-magnets-100-pack-strong-hold-corrosion-resistant","provider":"Cerva Australia | Professional Beauty Supplies, Skincare \u0026 Cosmetics","version":"1.0","type":"link"}
