DIYMAG Strong Magnets, 12 Pack with Double Sided Adhesive Backing Powerful

Bought these for adding magnetic cap catchers to wall mounted bottle openers, and they work absolutely fantastic for that, even with there still being about 1/8" of wood between the magnet and the caps. The magnets came well packaged, and it was clear just how strong these were even before opening the package, as I bought two boxes, and they kept sticking together (though easily enough to pull apart). The styrofoam liner in the box did a perfect job of keeping all of the magnets intact during shipping. The plastic discs separating the magnets well definitely super useful, as they made it relatively easy to slide individual magnets off the stack. I did have one get too close and slam back into the stack without a plastic disc in place, which resulted in a small chip in one magnet, and took a lot of work to get it back off the stack. That said, it was still perfectly usable afterward. I can't speak to the adhesive pads included with the magnets, as I have been gluing these in place for my projects. Overall, these are a good deal for how strong and well package they are.

Best magnets ever

I bought this six-pack of round magnets for a small DIY organization project where I needed a strong magnetic hold without using bulky hardware. The 1.26-inch diameter gave me enough surface area for the pieces I was attaching, while the 0.12-inch thickness kept everything fairly low profile. The magnets are noticeably stronger than the small craft magnets I had used before. I attached a few to lightweight organizers and tested them on a metal cabinet, and they held firmly when the contact surface was flat. The included double-sided adhesive backing was useful because I did not have to find separate tape for the non-metal side of my project. The smooth coated finish also makes them look cleaner than unfinished magnets. I like that the pack includes six identical pieces, giving me enough for several small projects without buying a large bulk set. The size works well for crafts, pictures, whiteboards, and simple organization jobs where a tiny magnet would not be enough. For what I needed, they were easy to use, compact, and surprisingly strong.

The DIYMAG 12Pack offers a set of neodymium disc magnets that are designed for heavy-duty use across a range of applications—from holding items on your refrigerator to use in DIY projects, scientific experiments, crafts, and office organization. Measuring 1.26 inches in diameter and 0.12 inches in height, these magnets promise impressive strength in a compact size. They come with a double-sided adhesive intended to facilitate easy mounting, making them a popular choice for a variety of creative and practical tasks. Pros • Exceptional Magnetic Strength: Users consistently highlight the powerful holding force of these neodymium magnets. They are capable of supporting significant weight and remain effective for both indoor and light outdoor applications. This makes them ideal for tasks ranging from mounting insulation boards on a fireplace to organizing office supplies. • Versatility: The magnets’ compact size and strong magnetic pull make them suitable for a wide variety of projects. Whether you’re working on craft projects, scientific experiments, or simple household fixes, these magnets offer the flexibility needed to tackle many tasks. • Ease of Installation: With the inclusion of a double-sided adhesive backing, these magnets are designed for quick and straightforward mounting on metal surfaces. This feature is particularly beneficial for applications where drilling or permanent fixtures are undesirable. Cons • Adhesive Quality Concerns: A recurring theme in customer feedback is the reliability of the double-sided adhesive. Several users have reported that the adhesive can lose its stickiness over time or fail to support the magnet’s weight consistently, leading some to seek alternative mounting solutions such as aftermarket 3M tapes. • Handling Difficulties: Due to the high magnetic pull, some users find that the magnets can be challenging to separate once they snap together. This extra strength, while a benefit in many contexts, may be inconvenient in applications where frequent repositioning is necessary. • Potential for Damage if Misused: There are occasional reports of magnets chipping or breaking if they are forced apart or if they collide with each other too forcefully. Care should be taken during handling to avoid such issues. Recommendations • For Heavy-Duty or Permanent Installations: Consider reinforcing the adhesive or replacing it with a high-quality alternative (such as 3M VHB tape) to ensure a long-lasting bond, especially if the magnets will be used in applications that require a secure, permanent hold. • For Projects Requiring Frequent Adjustments: Be aware that the strong magnetic attraction can make repositioning difficult. If your project requires frequent changes, you might need to plan for additional tools (like a thin pry tool) to help separate the magnets safely. • Handling and Storage: Store the magnets with a non-magnetic separator between them (such as thin plastic sheets) to prevent accidental snapping that might cause chipping or breakage. • Usage Environment: While these magnets perform exceptionally well in controlled indoor environments, prolonged exposure to moisture or outdoor elements might accelerate corrosion if the protective coating is compromised. For outdoor or high-humidity applications, consider additional protective measures. Conclusion The DIYMAG 12Pack Strong Neodymium Disc Magnets present a compelling option for DIY enthusiasts, crafters, and professionals alike due to their impressive magnetic strength and versatility. However, potential buyers should be mindful of the reported adhesive issues and handle the magnets with care to avoid damage. With some minor adjustments—such as upgrading the adhesive for more demanding applications—these magnets can serve as a reliable and powerful tool in a variety of situations.

Very strong, worked well for my project, good price.

There is no joke in saying these are powerful magnets. I got mine 10 minutes ago and I couldn't wait to play with them like a kid! I got them for my metal embroidery hoop. I wanted something strong to really hold down fabric because if it shifts mid-sewing, it can be ruined. I read what the seller said about using the spacers, I was putting the 6th one back on the stack to set down and from at least 6 inches away the 1 disc slipped out of my fingers and snapped onto the stack. It was the most powerful thing I've handled with magnets! I didn't mean to do it, of course. Then it took forEVER to break the top 2 apart. I couldn't slide it forward. I finally got it, but I think I wore out my right hand lol! I did a hand test where I put 1 on top of my hand and the other on my palm. The strength was definitely weaker, but it held. I don't have my metal hoop yet to say how good it is for my purposes. But like a kid, I kept trying different metals I have here on my desk. I will NOT try this on my fridge because I probably won't be able to get it back off. These aren't complaints, these are compliments. 1 disc did come with 2 chips in the edge, but it seems stable, they are very tiny. I can't image being the sorter who has to pry apart stacks of these for customers.

Be very careful. I took these magnets out of the package, and they are strong that they slammed into each other. Sparks flew and 2 of them shattered. It was actually painful. I can see where it could break a finger. I'm not being over dramatic. These are dangerous. I'm not saying, don't use it. The fact that they are super strong is a plus. I'm just posting this to make you aware of the danger. As you take each magnet out of the package, put it far away from you and the other magnets.

These are really nice, really strong little magnets! I got them to hold remotes for my adjustable bed. They work great!

Very difficult to separate but they are magnets, very strong so you can, if you are not careful, easily trap finger between them so be careful. I have stuck on inside kitchen cupboard for my good kitchen knives work very well

Thor's hammer has nothing on these little guys. Extremely powerful and strong. And the strength increases the more you stack together. They are about the same size as a quarter, but a little thicker. I recommend them for all your magnetic needs!

Really strong magnets.

extremely powerful

These magnets are very powerful and did exactly what I needed them to do, but a number of them snapped into pieces. Would not recommend for use in crafts or anything child- or pet-related.
