Okay, these little magnets are seriously powerful! Made from neodymium (the strongest type of magnet available), these small round discs pack unbelievable magnetic force. Measuring 0.4 inches in diameter and 0.15 inches thick (about 10mm x 3.8mm), they're perfect for so many uses. The main purpose? They work amazingly with metal collar stays to keep your shirt collars perfectly positioned all day. No more floppy collars or awkward collar gaps! But that's just the beginning - crafters will love these for all kinds of projects. They're great for women's hijabs, small DIY projects, workshop organization, you name it. You get 36 pieces in a handy storage case that keeps them organized and prevents them from sticking to everything. The smooth finish means they won't scratch surfaces, and the strength is just incredible for their size. Seriously, be careful handling these - they're so strong they can pinch if you're not careful! The quality is top-notch - no coating chips or weak spots. Whether you're upgrading your dress shirt game or need reliable small magnets for projects, these deliver professional-grade performance. They work through multiple layers of fabric too, so you can get creative with placements. Just remember - keep them away from electronics and credit cards! For the price and quantity, this is an absolute steal for such high-quality magnets.
