Each magnet dot with an adhesive backing that you can use when you need them. Professional Brand - TRYMAG Magnets. We are a professional ceramic magnets seller. Meeting every customer's needs is our service goal. High Quality 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. ## Features - 【High Quality】- Premium quality 300 PCs ceramic industrial magnets with 300 PCs double-sided adhesive.
