Bulk Pack: This set includes 10/20 pcs stainless steel blank coins, with sufficient quantity to fit bulk customization projects, group gifts and corporate brand promotion needs, no frequent restocking required. The coins are shipped in dedicated protective packaging, which helps prevent scratch damage during transportation
Precise Size & Sturdy Construction: Each set comes with 10/20 pcs blank challenge coins ready for engraving, with a diameter of 1.18 inches (30mm) and a thickness of 1/16 inch (2mm). The one-piece sturdy construction can withstand repeated engraving, stamping and other processing operations without deformation, providing a stable blank base for custom creation
304 Stainless Steel: Crafted from 304 stainless steel, the coins feature a wear-resistant matte black coating that effectively resists fingerprint and daily scratches. The non-reflective matte finish is distinct from polished glossy surfaces, delivering a distinctive visual texture. With non-magnetic and corrosion-resistant properties, the coins maintain colorfastness performance for long-term use, suitable for both indoor and outdoor applications
Compatible with Multiple Custom Crafts: The coin surface is professionally and finely treated, compatible with mainstream custom processes such as laser engraving and hand stamping. The smooth matte black surface creates a high contrast ratio, making the engraved/stamped patterns stand out clearly. We recommend using a CO2 laser for precise pattern marking or traditional metal stamps for a handcrafted texture
Multi-Scene DIY Gift: These blank coins are the ideal blanks for DIY customization, which can be made into exclusive challenge coins, jewelry accessories, keychains, custom tokens, golf ball markers and more, meeting the diverse needs of amateur handcraft lovers and professional custom practitioners.
