Okay, so these ceramic magnets are seriously strong for how affordable they are - you get 12 of them in this pack, each measuring about 1 7/8 inches by 7/8 inches by 3/8 inches. They're made from ferrite ceramic material which gives them really good magnetic strength without costing a fortune like some other types of magnets. I've used them for all kinds of projects - sticking things to the fridge, organizing tools in the garage, science experiments with my kids, even for some craft projects. The grip is surprisingly strong for their size, and they maintain their magnetism really well over time. They're highly resistant to demagnetization, corrosion, and oxidation, so you don't have to worry about them rusting or losing their power. I've had some on my fridge holding up heavy recipes and they haven't budged in months. They work great for organizing in workshops - you can stick tools to metal surfaces, hang things from metal shelves, all kinds of uses. The rectangular shape makes them more versatile than round magnets for certain projects too. What's nice is that they're durable enough for pretty much any environment - kitchen, garage, office, you name it. Grtard is actually a professional magnet company, so you're getting better quality than those random no-name magnets you find sometimes. I've used them for securing things on my grill during cookouts, holding papers on whiteboards, even for some DIY home decor projects. For the price, you're getting a lot of magnetic power that'll last. If you need reliable magnets for organizing, crafts, or just general around-the-house use, this 12-pack is definitely a solid choice that won't break the bank.
