MIN CI 100 Pcs Neodymium Disc 9mm x 3mm

These little buggers are STRONG. In fact, so strong that handling them can be a little tricky - just pulling one off the stack can be a challenge until you figure out some tricks. First, they're quite small (about the diameter of a pea, but cylindrical and smooth). They're surprisingly strong - they stick well to any ferrous metal (steel, not aluminum) and stick especially well to each other. And because they're small, it can be hard to get a good grip on one - to separate one from the stack, I kind of twist and slide one off the top, and slide it onto my thumbnail (it took me a few minutes to figure out how to pull one off successfully - maybe I just have big fingers?). If you set one down on a counter or work-area, it will quickly fly to any metal within 6-12 inches or so (and especially to other magnets) so if you are trying to set out a bunch of them, you need to space them at least 6 inches apart, and if you inadvertently move a metal tool nearby, they jump up and stick to it. I ordered 100 of the small (6 mm x 3 mm) magnets initially. I had zero defects, none: no chipped or crumbled edges at all, as described in a few other reviews. I'd say the first 100 I received were flawless. I just reordered 400 more for a project. If you need little magnets that really stick, these guys seem like a good choice.

I am absolutely thrilled with the MIN CI 100 Pcs Super Strong Neodymium Disc Small Magnets (6 mm x 3 mm)! These little magnets are perfect for my 3D printing projects.I use them to create removable parts in my prints, and they work like a charm. They’re small but incredibly strong, holding pieces together securely without any issues. I’ve been using them in everything from miniatures to more complex functional designs, and the magnets stay in place with no shifting, even in objects that get a bit of handling.What I really appreciate is how easy they are to incorporate into prints. I can easily embed them into my designs during the printing process, and they integrate perfectly every time. The strength of these magnets adds that extra level of precision and functionality to my 3D creations.I highly recommend these magnets for anyone into 3D printing—whether you're making models, functional parts, or creative designs, they are a must-have!

What can I say about these magnets? They work great! I use the magnets for a 3D character I'm 3D printing and producing. I use magnets to hold and turn the eyes. The size I ordered, 12x3mm, fit perfectly with my system.

These magnets are really strong. They work really well with out steel magnetic whiteboard. The only issue was the 2 broken pieces in the set. Otherwise these magnets are just what we were looking for.

These are strong, little, well made magnets. I use them to display photos on my frig. I highly recommend this product. They arrived on time and came with their own plastic locking case to keep them in. Well worth the price. Thank you seller and Amazon.

Amazing strong magnets for their size! I used them to make domino game racks. Great quality and great value for how many you get.

They're stronger than the cheap black coin magnets that come on arts and crafts stuff but I definitely would not call these "super strong". They're fine for holding a sheet of paper or a photo, but there are definitely way stronger rare earth magnets of smaller size out there. They worked fine for what I needed but they aren't thick enough to be considered "super strong". The 15mm x 2mm is literally the size of a penny, both in width and thickness. It also kind of annoying the seller is putting them on Amazon and not offering the sizes in metric AND empirical. I'll do your conversions for you. 1mm = .0393" or just over 1/32". So 2mm is just over 1/16". 15mm is .5895" or just over 1/2".

They're small and stick to ferrous metal. I would recommend you don't eat them, but otherwise they're fantastic! Glue them to things and have fun confusing your boomer parents! I do and it's a blast!!
