These are perfect for crafts. Pay attention to the size as they are very small

Got this size because another customer said they got them for the tiny ducks people leave behind on cruises (since they did away with the rubber ducks). They "do" the job, but one little bump and they fall right off. We actually just got back from a cruise, found a tiny duck, and they actually used one size up. (Which is what I thought I was buying.) So, in the end, I would go up one millimeter for the tiny ducks. Again, the ones I purchased DO the job. I just don't like how easily they can be bumped off.

These magnets are wonderful for putting at the bottom of your mini's bases. Something that one should keep in mind though is that these magnets are incredibly powerful. This is both a blessing and a potential issue for figure bases that may be elevated. It will keep your miniatures in place on magnetic surfaces, though if the base with a magnet is elevated, the magnetic flooring (or anything magnetic), may pull on the magnet itself which will ultimately rip the magnet out of the base if one does not use the proper gluing/adhesive method. This is in no way the product's fault, though it is something that one should know, especially if they are beginners with utilizing magnets for tabletop games. Overall, these magnets are a incredible deal, and the sheer amount of them will last for many of your projects.

Magnets are good and strong they are just very very small.

These are perfect for little resin ducks to hide on a cruise ship!!

These magnets definitely work, but the dimensional accuracy leaves much to be desired. I bought the 5mm x 1mm magnets, and the diameter was pretty much spot on, but the thickness measures 0.781mm as opposed to the advertised 1mm. For my application, inserts for 3D prints, this 0.219mm made all the difference. The reduced thickness also resulted in a slight but noticeable decrease in magnetic force. All in all, if exact dimensions don't matter, these work fine, but if you need something 1mm thick, then this isn't it.

Fairly strong magnetic and seem to fit about right

These are perfect for my Warhammer collection. I just super glued the to the bottom and can now easily place them on the metal trays in my carry case. The small minis only need one and the larger ones I put up to four. They are the perfect depth.
