Question: I want to use these to make bottlecap fridge magnets. Are they thick enough?
Document: Good value for the price. Strong enough to hold up the ceramic tile that I wanted to make into a magnet, and hold up some papers on the fridge as well.
We use them for fridge magnets, decorating, and costumes. Works great and I like the dimple in it. Great price.
Unlike other reviewers using them as fridge magnets, I purchased these for my son's science project. We did not abuse these magnets - no throwing them on the floor or anything like that. However, with what I would consider normal use, such as being stuck together and separated carefully for the purposes of the experiment, they started splintering and breaking within the first hour of opening the package.
I bought these to use on our cruise cabin door to hold up laminated signs I'd made. I read a lot of reviews for other magnets and these were the ones recommended for what I wanted. It turns out that these are amazing little magnets! They were perfect for what we originally bought them for. But now, we're finding all sorts of use for them, including replacing magnet clips for holding things on the fridge, etc. Highly recommended to anyone looking for a strong little magnet!
SO STRONG! i use them for the back of buttons to make them magnets. i was shocked how strong they are. now i use them for everything.
These are good magnets and strong enough for most uses. They are dirty so your fingers will get dirty when you use them. The coated ones would be a better choice if that was a concern.
I originally bought these for my granddaughter to experiment with (with close adult supervision, of course). But I can't let her use them - they are so strong that they snap together with enough force to painfully pinch the skin on my fingers, let alone her smaller fingers. Oh well, I guess I'll be the one to play with them. (Ouch!)
As powerful as the magnet of Rokform for iPhone if not better. There is a $10 each magnet to attach the magnet in a Rokform case for iPhone, and instead of buying it I bought this. It holds my iPhone even when I use it on my moving vehicle--in fact I can put it anywhere--  it is small enough to be unnoticeable. Too bad it is not thin enough to fit on my iPhone case or I will be making a lot of money.
Definitely very very strong. But I do wish its a little thinner, however I knew the size when ordered. Made nice fridge magnets that won't fall off.
I got these to make some DIY glass magnets and they work great, very strong! I would but them again.
Answer: Hi! Yes they are! Hope this helps! Good luck!
