Great for the office whiteboard

We use these in our conference room. They stick firmly even through thick stacks of paper. Only giving 4 stars because I wish the set came in more varied colors.

Perfect for craft projects

As a teacher, I needed magnets that wouldn't fall off when kids bump the board. These are perfect. Super suction just as described.

Best value for money

Compared to other brands, these offer much better holding power for the price. The round design is comfortable to grip and remove.

Exceeded expectations

I was skeptical about the 'super suction' claim, but these really do hold tight. Using them on my garage tool board and they haven't moved an inch.

Incredibly strong hold!

I bought these to organize my kitchen fridge and they are amazing. They hold up heavy recipe books without slipping. The black finish looks very sleek too.

Good but be careful

They are very strong, maybe too strong. You have to slide them off rather than pull straight back or you might pinch your finger. Otherwise, they work well.

5 FAQ

Q: Will these magnets work on a glass whiteboard?

A: Yes, provided the glass is not too thick. For standard glass whiteboards (up to 6mm), these magnets provide a secure hold.

Q: Can I buy individual replacements if I lose one?

A: Currently, we sell these in sets of 12 only. However, the durability is high, so replacements are rarely needed.

Q: What is the thickness of the magnet itself?

A: The magnet core is approximately 5mm thick, with an additional 1mm plastic coating on each side, making the total thickness about 7mm.

Q: Do these leave marks on the fridge surface?

A: No, the smooth epoxy coating is designed to be non-scratch and will not leave residue or marks on metal surfaces.

Q: Are these magnets safe to use around credit cards?

A: While coated, these are strong neodymium magnets. We recommend keeping them at least 3 inches away from credit cards, hard drives, and pacemakers to prevent data loss or interference.
