What to know before buying

Listing details to confirm

Listing details are inconsistent about the material and magnet type: the specifications say ceramic, while a feature describes ferrite-process magnets and an item highlight calls them neodymium. The supplied dimensions also use 0.7 inches as the length, while the title calls it a 0.7-inch magnet. Confirm the selected listing details if these distinctions matter. For adhesive use, the listing recommends waiting about 12 hours before hanging objects.

Who is it for?

A good fit for

Small craft and classroom projects where a batch of small round magnets is useful.
Attaching magnets to non-magnetic craft materials using the supplied double-sided stickers.

Less suited to

Buyers who need consistent, specified magnetic strength or a confirmed magnet composition.
Projects where breakage or black residue would be unacceptable.
