DIYMAG Small Rare Earth Magnets, 40 Pack, 5 Sizes - Neodymium Magnets

Product description

Are these heavy‑duty strong neodymium magnets for holding heavy objects?

Small magnets for light DIY, crafts & decor. Attract each other, but hold only lightweight items like paper, photos & small ornaments. NOT for heavy objects, thick materials, or stainless/glass fridges
Why are these magnets weak on my stainless‑steel fridge?

Stainless-steel surfaces (especially brushed) have low magnetic permeability, which greatly reduces holding force. Best on ordinary carbon-steel surfaces for light crafts. Magnet-to-magnet is much stronger than to external metal.
Will the magnets chip or crack easily?

Neodymium magnets are brittle ceramic‑like material. Different‑size magnet will generate large impact force when snapping together quickly and may chip or crack. Please separate them slowly and avoid letting them snap violently against each other.
What are these magnets best used for?

Great for craft projects, 3D-print fixing, laser engraving for paper & leather, fridge photo decor, small DIY mods & science experiments. Perfect when you need multiple small magnet sizes for hobby work. Not for industrial heavy-load use.
