N52 5/16" x 1/4" magnets
These are strong magnets! Not toys! Should be great for my application as a magnetic closures for wooden boxes where I can cover the magnets with this veneer and still get good closure.

Strong and Dependable
These magnets are surprisingly strong for their size. They are often difficult to separate from each other by hand due to their great surface strength. Upon handling these over time, they do tend to chip and flake like any other magnet. Overall, a great bang for your buck!

Keeps my business coming back.
I’ve ordered these specific magnets on three separate occasions, bringing the amount of magnets I have ordered to 1650 total. They are exactly the right strength and size that I need, and they are consistently the same every time. They arrive in mint condition, and are packaged very well. I have no complaints about this company, and will continue to order from them in the future.
They could however work on their Internet page which takes the consumer through the process of leaving a review. There is some computer problem which doesn’t allow the review were to write in the correct box. I should note, I am doing this from a mobile phone. This is the second review I have left, and this has been a problem both times. -
All good
You get what you pay for, and it’s worth it with these magnets

Best value when compared to other sellers
These magnets were exactly what I was hoping they would be, and had the desired effect. They were cheaper than 6 other sites I reviewed when comparing magnet type, size, and strength.
