TIMHLOYINI 300-Piece Neodymium Disc Magnets, 3 Sizes, 2 mm Thick
Product description
Three diameters in one set make it easier to match small magnets to different craft pockets, printed parts, or display pieces. The flat, 2 mm-thick discs are designed for compact projects where a clip or bulky fastener would get in the way.
The assortment includes 120 magnets measuring 3x2 mm, 100 measuring 4x2 mm, and 80 measuring 5x2 mm. Which size fits your project depends on the opening, surface contact, and item being held, so the mix is useful for comparing options before settling on one.
The magnets have a silver-tone Ni-Cu-Ni plated finish and come in a clear storage case. Buyer feedback is mixed on both strength and size: some find them useful for small crafts, while others say they are smaller or less strong than expected.
How to use it
Choose the diameter that fits the available space: the 3x2 mm discs suit tighter insert points, while the larger 4x2 mm and 5x2 mm options offer more face area. They can be used in 3D-printed projects, miniatures, fridge crafts, labels, and other DIY work. For a practical example, a maker could test the three sizes in a printed pocket before choosing which to use across a batch.
Holding depends on the magnet size, the contact area, the surface, and the weight of the item. Test the setup before final use, especially if the magnet will sit behind a layer of material. These magnets attach to magnetic metal surfaces, a nonmetal surface may need a metal plate. They are small parts, so keep them away from children under 14. The product information also advises keeping them at least 12 inches from pacemakers, credit cards, mechanical watches, and electronic devices, and sliding them apart to reduce snapping or chipping.
Where it shines
The main advantage is having three diameters ready for projects with different fitting needs, rather than buying a single size before knowing which one works. That can be useful for craft batches, small repairs, miniature builds, or trials with 3D-printed inserts. The clear case helps keep the sizes together between sessions.
It makes sense if you need small round magnets for compact indoor projects and want a few diameters to compare. For notes or photos on a fridge or whiteboard, the surface must be magnetic, and the item’s weight and contact area still matter. If a project needs a predictable hold through thicker material or for a heavier object, a larger magnet or a different fastening approach may be a better fit. It might not be a great match if you expect these mini discs to hold substantial weight without testing.

Should you buy it?
This set is suited to makers who need small magnets for crafts, miniatures, printed parts, or light organization and would benefit from testing three diameters. The mixed buyer feedback is worth keeping in mind: reported experiences with size and holding strength differ, and the product details also tie hold to the surface, contact area, magnet size, and load. Choose it for compact projects where you can test the fit and hold before committing, for a more demanding application, select a fastening solution specified for that use.
