Rare Earth Magnets - Strong Holding Power These high-powered disc magnets are incredibly strong and commonly used in DIY, crafts, furniture design, fixings, kitchen design, sale display units, scale models, lock mechanisms, science experiments, computing and many more. Misconception It’s easy to assume that these magnets should be as strong as steel, Unfortunately, that assumption couldn’t be further from the truth. Many common metals are fairly ductile. If the material is ductile, that means you can bend or reshape it before it breaks. Steel or aluminum are ductile metals. Neodymium magnets are more like ceramic than a piece of steel. So it breaks more easily! Review: Little magnets with big attraction!! - Solid little magnets with big power! The adjective tape fixes to one part (in my case, a metal sign - which also would have been just as effective without the adhesive tape as it was attaching to metal) and the other to hidden screws so the sign could be attached and removed easily. Very easy to install (although they are so powerful you have to keep them well apart until ready!) and they are nice and thin at 3mm. Great value for money and very versatile! Review: These magnets have real pulling power! - We needed some magnets that definitely stuck to steel through a couple of layers of polythene insulation. The added problem was that there was only a narrow gap for us to put the magnets on. After careful use of two layers of aluminium tape for each of the 16 magnets in this pack, our problem was resolved. Unlike so many magnets we have used in the past which can be brittle if dropped, these are smooth on all sides, so don't look as if they will flake when coming sharply into contact with other magnetic items; I think they will be solid enough to last. They are a perfect size for what we need, and we will probably be ordering more, as they seem a bargain! (Basically, the insulated windscreen cover was not as snug a fit as we wanted, and it let in too much light. Careful placing of these around the edges quickly sorted it.) They are small enough so as not to get stuck on every steel item nearby, but still work extremely well. ## Features - ⭐【MAGNETS COATED】 - You will love the smooth and shiny finish.

The 4 were packed well to a point. Unfortunately I struggled to get them out of their bag. And as I did so, the magnets flew out of their individual foams, stuck themselves together so violently that 1 magnets chipped severely ans the chip flew and hit my face. Then they proved to be so strong my arthritic hands could not separate them and I needed help. (Even the friend who helped me was impressed with their strength). I wish they were packaged in a slightly larger bag to help make it easier to get at them. Defo value for money. Will defo hold up fairly heavy jars by their lids to bottom of a high shelf. I recommend but please take care when opening them. Don't get injured like me. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/463337016-4-pack-strong-magnet-30-x-3mm-8kg-pull-super](https://www.desertcart.us/products/463337016-4-pack-strong-magnet-30-x-3mm-8kg-pull-super) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-24*
