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!

These tiny magnets are exactly what I needed for my handmade clay refrigerator magnets. They’re small but surprisingly strong, and they hold up heavier pieces without slipping. The size is perfect — discreet and easy to attach with glue. Great quality and very reliable for craft projects!

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.
