- 50 Pcs Super Strong Neodymium Disc Magnets, 15mm x 2mm Tiny Small Magnets for Dry Erase Board Whiteboard Office Fridge Crafts, Heavy Duty Round Rare Earth Magnets for DIY Scientific Models

Neodymium rare earth magnets are one of those items where the quality difference between a well-manufactured product and a poorly-manufactured one is not visible to the eye but is immediately apparent in performance. I work on a variety of maker and DIY projects where magnets serve as fastening mechanisms, sensors, jigs, and organizational tools, and I have accumulated enough experience with different quality levels to give this 100-piece set a meaningful evaluation. This is a 100-piece set of round neodymium magnets, small format, designed for a wide range of applications from refrigerator organization to craft projects to hobby builds. The neodymium composition is N52 or similar high-grade rare earth magnet material, which provides substantially higher magnetic field strength per unit volume than ceramic or ferrite magnets of the same size. The difference is significant in practice, with neodymium magnets of this size holding several times the weight capacity of comparably-sized lower-grade magnets. The pieces in the set I received are dimensionally consistent. When you buy a large quantity pack of small magnets, one of the reliability concerns is whether all pieces are the same size or whether there is variation that would cause problems in applications requiring tight tolerances. These measure consistently in both diameter and thickness within the precision that matters for standard DIY applications. Magnetic strength is strong and consistent across the pieces in the set. Testing individual pieces against a steel surface and against each other, the force felt equivalent and the snap engagement that characterizes a quality neodymium magnet was present on all pieces. Weak or off-specification magnets in a bulk pack would feel noticeably different in hand tests and I did not encounter any in this set. Packaging keeps the magnets organized and protected, which matters for neodymium magnets specifically because they are brittle and chip or crack if they are allowed to snap together at speed from any significant distance. Proper storage and careful handling are important with neodymium to maintain their integrity. For maker projects, organization boards, craft applications, or any use case where you need a reliable supply of consistent-strength small rare earth magnets, this 100-piece set delivers on the critical performance requirements.

I'm thoroughly impressed with the MIN CI100 Pcs Strong Round Small Rare Earth Magnets! These tiny magnets pack a big punch and have become an essential tool for my daily tasks. Pros: Strong and reliable: These neodymium magnets are incredibly strong, holding my notes, reminders, and even small items like keys and clips on my metal door, fridge, and whiteboard with ease. Compact and versatile: The small size (8mm x3mm) makes them perfect for various applications, from crafting and DIY projects to office organization and home decor. Durable and well-made: The magnets feel sturdy and well-constructed, with a smooth, corrosion-resistant coating that prevents chipping or rust. Great value: With100 magnets in a pack, you can experiment with different uses and share some with friends or family members. Comes with a storage container: I appreciate that the seller includes a small container to store the magnets, keeping them organized and preventing loss. Cons: None notable Use cases: Holding notes, reminders, and to-do lists on metal surfaces Crafting and DIY projects, such as making jewelry, decorations, or models Organizing office supplies, like paper clips, pushpins, or small tools Creating a magnetic board for displaying photos, artwork, or schedules Tips and recommendations: Use these magnets on ferrous metal surfaces, such as steel, iron, or nickel, for optimal performance. Experiment with different configurations and arrangements to maximize their holding power. Overall, I'm extremely satisfied with the MIN CI100 Pcs Strong Round Small Rare Earth Magnets. They're a valuable addition to my daily routine, and I highly recommend them to anyone seeking reliable, compact, and powerful magnets for various applications. UPDATE: I've been using these magnets for a few weeks now, and they've performed consistently well. I've even used them to create a magnetic board for my kids' artwork, which has been a huge hit!

These magnets are great! I bought these for a board game I am creating and needed something to connect the pieces all together. The dimensions and tolerances on each piece are spectacular and these things are unbelievably strong! The only downside that I have noticed is honestly how strong they are relative to their size. The magnetic field of these are so strong that if you're not careful, when they snap together they will split in half or chip off small pieces. So, with that in mind, if you are looking for a strong magnet, this is the way to go!

I have ordered these on three occasions - all for gluing to ducks to hide while on a cruise. They're really surprisingly strong for their tiny size, they barely They're very small - which is just what I needed. A few of the magnets starting chipping along the edges. The tiny chipped pieces were still magnetic but seemed more of a danger as tiny slivers. Definitely too small to have around young kiddos or pets, great for crafts.

LOVE these! They are surprisingly very strong for how small they are. I use them all the time and am almost out, so I am definitely going to need some more! I will say they work best with thinner objects, but overall great quality and great product.

Dimensionally accurate (read description 6mm is small). Strong for their size. Item didn't ship on time, but I think it was a problem with Amazon not the seller.

I didn’t read the description closely enough. These magnets are strong but very small (smaller than a tic tac or pencil eraser). I bought them to hold up photos and cards in the refrigerator, which they do, but they are easily lost if they get knocked off.

I use these for my 3D prints and they seem true to size. Fits on all the models I have printed so far. Its magnetic strength strong for its size and it is true to size.

Dimensions: 8mmx2.95mm, close enough for me to be used in my 3D prints, nice and strong, especially for their small size.

These magnets are very strong. Using for fridge magnets.

Very strong for small magnets and they appear to be well and consistently made. I find that 3 of these embedded on the back of a fridge magnet ensure very good attachment for a small stack of papers.

I was really disappointed with the MIN CI 100 Pcs Super Strong Neodymium Disc Magnets. Despite being advertised as “super strong,” they’re actually very weak and can barely hold anything in place. Even lightweight items slip off easily, which defeats the purpose of buying heavy-duty magnets. To make things worse, the price is far too high for what you get. The quality and strength don’t come close to other neodymium magnets I’ve purchased in the past. Overall, these magnets are a big letdown — definitely not worth the cost. I wouldn’t recommend them if you need anything remotely strong or reliable.

Just as advertised super strong magnets.
