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: Adhesive included. Not powerful magnets but great for the price. - Great lil magnets for my purpose 👌🏾
