How is the quality of fridge magnets? Small does not mean weak!Our fridge magnets are designed with quality in mind, ensuring they are both durable and reliable. They can hold up to 12+ sheets of A4 paper or 30+ sheets of sticky notes on whiteboard. How strong are these magnets? Can they hold up heavy items like a set of keys? Our magnetic thumbtacks are designed with neodymium magnets, which are some of the strongest available for their size. They can hold up items weighing up to 1 pound, making them perfect for keys, small kitchen utensils, and office supplies. Are there any special considerations I should be aware of when using magnetic thumbtacks? We've noticed a lot of customers mention this issue! We recommend that when using, gently attach the magnetic thumbtack to the metal surface to avoid sliding, which can reduce any possible wear. Are there different sizes or only one standard size? Of course, we offer a range of magnetic thumbtacks in different sizes to meet a variety of different use needs. We also provide detailed guidelines to help you choose the right magnetic force and size for your specific application.
