Perfect for crafting

Used these for a DIY magnetic board project. The nickel coating looks sleek and professional. They arrived well-packaged and separated individually.

Strong but brittle

They work great, but one cracked when I accidentally dropped it on the tile floor. Just remember they are ceramic-like in brittleness despite being metal.

Good quality, handle with care

These are very strong neodymium magnets. You need to be careful when separating them so they don't snap together and chip. Perfect for my workshop organization.

Best magnets I've bought

I use these to secure tools in my van. They haven't lost any strength over the last few months of daily use. Will definitely buy again.

Incredibly strong for the size

I was surprised by how powerful these little magnets are. They hold up my heavy photos on the fridge without sliding down. Great value for the price.

5 FAQ

Q: Can these be used outdoors in the rain?

A: The nickel coating provides good corrosion resistance, but prolonged exposure to water or humidity may eventually cause rusting. We suggest sealing them if used in wet environments.

Q: Do you sell larger sizes in this series?

A: Yes, we offer various sizes in the Rectangular Magnet Series. Please check our store catalog under the 'Magnets & Magnetic Balls' category for 12mm and 15mm options.

Q: Are these magnets safe to use near electronics?

A: While they are safe for general use, we recommend keeping them at least 6 inches away from sensitive electronics like hard drives or pacemakers due to their strong magnetic field.

Q: How are they packaged to prevent snapping?

A: Each magnet is individually spaced with cardboard dividers inside a sturdy box to prevent them from attracting each other during shipping and to ensure they arrive intact.

Q: What is the exact pull force on steel?

A: On a thick, flat steel surface, the vertical pull force is approximately 4.5 lbs. This may vary depending on the thickness and type of the metal surface.
