They're magnets by J. Baas (Taylor, MI United States)  5 Stars
November 11, 2009
As the other reviews of these handy little magnets suggest, they are very strong. You have to twist them to get them apart. I used two of these tiny things to attach a decorative wall plaque to the side of a locker.

Great! by Palm Trees (New Jersey) 5 Stars
September 16, 2009
I bought these to hold an aluminum gas door closed on my truck after the original spring broke. They show a picture of the magnets holding together through a penny so I figured I'd give them a try after using hook and loop first and having it fail due to exposure to the elements. I got the tiny 1/4 inch ones and used epoxy to clue them on the door. They worked so perfectly and I found so many other uses for them I actually ordered two different sizes to add to my collection. They are so strong that even the tiniest ones will hold through multiple sheets of paper on your fridge, I've glued them to bottle openers and also to my BBQ tools to stick right on the side of my grille. I love these things and can't believe I never discovered them before.

Tiny but very very strong. by David (Southern California) 5 Stars
January 28, 2009
These little magnets are incredibly strong. I wanted something that would allow me to display metal signs and license plates on some metal cabinets in my garage. These do the trick, and are far superior to screws or tape. Two to four magnets will hold each item in place, and they can be removed with no marks or damage. I just ordered another 30.

Strong! by Shalla DeGuzman (Bamberg, Germany) 5 Stars
January 06, 2009
I'm sure there are stronger magnets out there but this is a good buy. it's about a quarter of an inch thick so it's thick and won't break or crack.
I'm studying magnetic therapy (I have a magnetic pillow I've had for years which I swear loosens up my back but I got it for about $150.00 so I'm reading up on magnetic therapy to maybe make my own pillows for my pets and I.
I realize there are magentic therapy magnets sold but I'm gettting a feeling they're just magnets like these only gold colored..."Applied Magnets" - MAGNETIC THERAPY FOR PAIN RELIEF 24kt Gold Coated 1" x 1/8" Rare Earth Neodymium Therapy Magnet

Excellent strength with compact size by J. W. Theis (Fairbanks, AK USA) 5 Stars
November 25, 2008
I purchased these magnets with the intent to use them for attaching photos and papers to a steel filing cabinet. My goal was to find something small enough to not obscure the photos, but strong enough to hold them steady in a well-used, fast-paced environment.
These buggers certainly do the trick. To give a reasonable idea of the magnets' strength, a single magnet will comfortably hold ten sheets of paper without sliding. I think, regardless of size, users will find it difficult to remove the magnets (when applied directly to a surface) without sliding them to an edge or using a small wedge, such as (strong) fingernails, a file, etc. The magnets' appearance is as attractive as their disposition. They are moderately durable; I dropped several on my concrete floor from about 4 feet up and they weathered the event without any chips.
When I need more, these will certainly be the first in my shopping cart.
