For all my crafters and DIY enthusiasts out there, these brass coin blanks are absolutely perfect for creating custom keepsakes! Each pack comes with six high-density solid brass coins that have this beautiful golden luster - they feel substantial and quality in your hand. At 40mm in diameter and 3mm thick, they're the perfect size for detailed engravings without being too bulky. The threaded edges add a professional touch and make them great for turning into keychains or necklaces later. What's really awesome is that both sides are ready for engraving, so you can create intricate designs, logos, or text on either surface. I've used them with both laser engravers and traditional etching tools, and the brass takes the designs beautifully with crisp, clear results. The included acrylic storage boxes are a nice touch - they keep your finished coins protected from scratches and oxidation while displaying them nicely. I've made custom coins for my team at work, wedding favors for friends, and even pet memorial coins, and everyone has been amazed at how professional they look. The brass is durable and won't break or fade over time, making these perfect for heirlooms or long-term collections. Whether you're making challenge coins for your organization, commemorative pieces for events, or just want to create unique gifts, these blanks give you the perfect canvas to work with. The quality is much higher than I expected for the price, and having six to work with means you can practice and perfect your designs. If you're into custom crafting or need professional-looking tokens for your group, these coin blanks are definitely worth trying out!
