Wukong Super Strong Magnets, 20x4 mm | 10 Pack Heavy Duty Round Magnets for Fridge, Crafts, Pin Board, Notice Board, Office Crafts

A bit pricey, but they're very strong and they're very handy to have.

I used these for bike lights on bags. Two magnets one inside bag, one one bike light on the outside. The sticky pads are not that sticky. Probably ok on something that wont be moving. The magnets are very strong. Be careful not to slap them them together, or they will shatter.

Weren’t quite fit for what I wanted them for but they were surprisingly strong for such a small magnet

I’m building shutters for my house and needed some magnets to hold them closed.These are quite simply amazing! I’m building one magnet into a secret pocket in the frame, and another into the shutter itself, and these are more than strong enough for the job.Don’t waste money on inferior items, these are all you’ll need!

The magnets seem to have pretty good and consistent pull strength and they were pretty cheap.However the material quality and manufacturing process leave much to be desired.Almost all the individual magnets were delivered with significant surface defects ranging from multiple small indentations across the disc to having large sections missing presumably due to damaged formers or contaminated materials being used.At the time of writing nine of the twenty magnets have shattered into multiple pieces, again this seems to be due to low quality base materials and/ or poor manufacturing.

Strong enough for my requirements.

Not great quality. My son opened his present yesterday and 10 magnets snapped in half when he was playing with them. They are too thin for the force of the magnets.

Strong magnets for the size, good adhesion and looks like they are perfect for my application.

These are strong and sturdy magnets and just as described.

Ottimo prodotto. Consigliato!

Die Magneten sind zwar nicht besonders groß aber dafür wirklich sehr kräftig. Bin sehr zufrieden damit und erfüllen genau den Zweck wofür ich sie brauche.

Et pourtant tout petits, je les utilise sur le frigo, et surtout pour fixer mes feuilles lorsque je fais des aquarelles, beaucoup plus écologique que le ruban masqueur même si c’est expédié depuis la Chine, dans le temps l’empreinte carbone c’est zéro !

Starka för att vara så små.
