TRYMAG Magnets for Crafts 0.7x0.12In Strong Magnet 20Pcs Magnetic Circle Adhesive Small Craft Round Fridge Backing Mini Button Ceramic Sticky Circles Magnetics Neodymium Heavy Duty Strips Dots 18x3mm: desertcart.com: Industrial & Scientific

Review: Great quality - both magnet and adhesive! - In the 3 boxes of these that we’ve bought, we’ve been incredibly impressed with the adhesive strength and durability. Once they are stuck to something, it’s not going anywhere! (Be careful to stick them where you mean to, because they are VERY hard to remove!) The magnets and adhesive circles were exactly the size we expected - about the size of a dime, but thicker - and we were surprised how strong they hold to the fridge for their size. My son used these to make and sell fridge magnets, and they have held up so well after a couple years that he is still in business with repeat customers. We will definitely be ordering these again - this time in the larger quality because they are even cheaper per unit!
Review: Well-made magnets - I've used 7/8" magnets in my craft for years, but evidently those aren't available anymore. These are smaller at only 18 mm, probably not quite as powerful as 7/8, but strong enough for most of my uses. I adhere magnets to my crafts using E-6000 adhesive so I was happy when I received them without the glue pads already applied. I was afraid I was going to need to scrape a glue pad off of each magnet. They are well made, better than expected, but I wish there was a dimple or paint spot to indicate polarity like the other magnet sizes I use.

### ⭐⭐⭐⭐ Great magnets
*by A***H on February 1, 2026*

Great magnets. I got them to stick to ceramic magnets I made. They stick wonderfully without me having to add any glue. I love that they come in all sorts of sizes. I wish there was a few more bigger ones and less small ones. However the magnets hold for a long time. I have had them on for over a 2 years and not had them fail. I sometimes put 2 magnets on 1 piece if it is large. And they are thin so they are not super noticeable.
