### ⭐⭐⭐⭐⭐ Nice and strong. accurate size.

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.
