Question: I am making a fishing game for my grandkids. crochet fish with a washer in the mouth. I need a strong magnet for the "hook" are these strong enough ?
Document: Another item I purchased and didn't really need? But these have been such a blessing for the fridge at home. They are small, very small. Smaller than the fridge magnet's you're use to. But they are very strong, enough in fact to hold 6 sheets of paper with one magnet.Very impressed with these. I would recommend these to anyone.
These magnets are quite a bit smaller than I expected. I really need to put a ruler next to my computer when shopping. They are, however, very strong. I will just use two of them on the larger decorative refrigerator magnets that I am making.
These magnetics are the absolute best. I used them for making magnetic planters out of wine corks for my fridge and they work perfectly. Previous reviewers are completely accurate. These magnets are tiny. About the width of a pencil eraser. These magnets are also ridiculous strong. They can be hard to remove from the fridge until you get a trick down. If you are looking for an ultra strong tiny magnet this is it!
Like the title said, the magnets were very small but very powerful. They definitely did the job(I was making fridge magnets with clothespins. )You'll need something stronger than regular glue or hot glue. Super glue is what I found worked best.
taping the magnet near the mouth piece holds steal darts until I wish to shoot them.makes blow guns a lot more user friendly.
I use these with some other magnets to customize miniatures for swapping weapon load-outs/ faces etc. These are larger than most of the magnets you should use for minis and are really applicable for vehicles and larger models that need a stronger pull in order to keep their position maintained. These are not strong enough to injure yourself if you are careful and keep away from small children. Easiest way to separate is to slide the magnets apart instead of pulling since the polarities are weaker on the edges.
Not strong enough need to be bigger. Already lost two.
Works as advertised. For a reference of how small it is - a penny is probably 4x the size of this.Pretty strong, though I find one magnet can only hold something as thick as a standard photo, any thicker and you need additional magnets.
These suckers may be itty bitty but are super strong. One magnet can hold a card on my fridge. At first I was a little turned off by their size when buying them but after reading reviews I took a chance. It was worth it because these magnets really do hold just about anything I need them to.
These babies are small! Really small. I would not leave them near children. The size of a watch battery. But super strong. I put three magnets on my metal door and it held a butcher knife! Securely! That is not what I am using them for now. I have papers for my office space on a metal cabinet and i only need one magnet for up to 6 sheets with paperclip. Great product.
Answer: Yes they are... but be extremely careful using magnets like this around small children.  If they swallow one magnet, it can cause problems....   if they swallow two strong little magnets... it can be fatal.  The two little magnets WILL find each other, and in the process they can tear holes in intestines or other body organs.  I would urge you to use extreme caution when using rare earth magnets around small children.
