RHINOCATS 400Pcs Small Magnets, 4 Different Sizes Tiny Mini Magents, Multi-Use for Fridge, DIY, Office, Hobbies, Crafts and Science

Thank you for your honesty! They measure about 1.96mm thickness, which is super close to 2mm! And thanks for the vinyl touch in the packaging:) Will buy again later (probably in bulk). I suffered from very bad tolerances on other listings, they were much thinner than listed, but this is actually accurate and honest. Glad I found it! 🥳

These RHINOCATS 400Pcs Tiny Magnets have been working perfectly in my 3D prints. The variety of sizes is super handy, especially when you are working on different models or parts that need different levels of hold. Despite their small size, these magnets pack a strong grip and stay firmly in place once installed. I’ve used them for everything from lids and enclosures to tool holders, and they’ve never let me down. The quality feels solid, and I haven't had any issues with chipping or demagnetizing. Great value for the amount you get, too. If you're doing any kind of 3D printing that involves modular parts or closures, I highly recommend these.

I use these 6x3mm as embedded magnets for 3d prints. They are quite strong. The size is slightly off by 0.1mm across batches, but for the same batch they are consistently sized.

These tiny little magnets pack a punch despite their size, Four shapes, four strengths—each one a classroom prize. They’re perfect on my whiteboard, holding papers strong and tight— Strong, small, dependable… they keep our charts just right! For teachers needing power in a magnet that won’t fall— These RHINOCATS are mighty, though they’re really very small!

Use them in 3d printing and they function well for that. They appear to be dimensionally accurate, though I didn't check all of them, just enough to double check. Packaging leaves something to be desired, mine showed up in a metal box with foam leaving a big ball of magnets to go through. They stick together and stick to metal, so they work, not the strongest but they are small so, not really anything against them.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

I purchased thes to install on my N-scale steam locomotives. I run a lot of older 4-4-0, 2-6-4, 0-6-0 steam engines on my layout. The assoted sizes alow for finding the right strength and size to glue to my undercarraige of the loco. Of course they wont work without having something to attract to so I also install a thin 0.025 piano wire in the center of my track. This is installed in areas that have a grade or where there is difficulty with traction in pulling a realistic number of passenger, freight, or ore cars for the given engine. Not many of these steam engines can do much without some means to increase traction. The magnets are unseen and provide a downward force on the traction wheels which indeed helps the pulling power and effectivness of the locomotives. My track was already layed but if you are installing new you may find it resonable to install strips of light steel sheet that can be cut with shears and placed under your track to provide for the attaction. This system will work for most any scale just size accordingly to the size needed. By the way Amazon also proovides the small piano wire in differnt lengths. I used 36-inch.

Perfect for repairing a cabinet door where the magnets fell out. But now what do I do with the other 398 pieces?!
