I used one to hold a security camera to the ceiling and it does the job very well. I don’t think one could hold 8 KGs, but two together may be able to. ### ⭐⭐⭐⭐⭐ Nice and strong. accurate size. *by M***N on 9 March 2026* very strong magnetic force. suitably packaged. accurate dimensions. inserted into 3d prints to make tool holders. ### ⭐⭐⭐⭐ Very strong shallow magnets *by G***S on 7 June 2025* Very strong magnets for the size. 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.id/products/463337016-4-pack-strong-magnet-30-x-3-mm-8-kg](https://www.desertcart.id/products/463337016-4-pack-strong-magnet-30-x-3-mm-8-kg) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
