Grtard 20Pack 15x3mm Small Magnets Tiny Magnets Mini Magnets, Strong Round Small Magnets for Crafts, DIY, Whiteboard and Map, Office Button Magnets

The magnets are brittle and are so strong, when they attract, they can hit each other and shatter. Overall very happy with these magnets.

I had a problem with an interior door frame getting out of square due to slab issues. I installed those cool little square magnets that you screw into the door and the frame, but the gap was too wide to work. I slipped two of these little power buttons in the right place and it works like a charm. I put the rest of the stack in a safe place and if I need to replace one from time to time, I am covered. Wife thinks I am en engineering genius. I told her yesterday I could not spell engineer, but today I are one. All jokes aside, these magnets come well packaged, in great shape and are stronger than you think.

They are a little smaller than I thought, but extremely strong

7 out of 20 arrived shattered in pieces. Extremely fragile.

Sometimes use these for my DnD game to hold the battle map on a whiteboard. They work well. They are a little brittle, though, so I would not recommend using them as fidget toys

I just got these in the mail. Haven’t even used them yet and they are already breaking chunks off.

These little magnets have a good amount of holding power, but don’t even think about dropping one! They break SO easily! For that reason, we ended up not using them for what we bought them for.

These are perfectly sized for the project I needed them for, and work beautifully. Love the little container they were in, also.
