21 Pcs Blank Challenge Coins for Laser Engraving, 40mm Metal Engravable Blanks with Acrylic Case - 7 Colors Custom Coin Blanks for DIY Crafts, Personalized Gifts & Commemorative Challenge Coins

Unlock your creativity with this **21-Piece 7-Color Blank Challenge Coin Set** — the ultimate starter pack for laser engraving, metal stamping, and custom coin crafting. What sets this kit apart is the **7-color variety**. Instead of buying single-color bulk packs, you get matte and glossy gold, silver, nickel, antique copper, red bronze, and green bronze — three coins each — so you can match any theme, try different finishes, and offer clients real options. Each 40mm × 2.5mm blank is precision-cut from durable alloy with a smooth double-sided surface that captures every engraving detail with professional clarity. Every coin arrives in its own **transparent acrylic protective case**, guarding against scratches and oxidation before use — no more arriving with dinged edges or smudged surfaces. The 2.5mm thickness gives each coin satisfying heft while remaining perfectly compatible with most home and workshop engravers (CO2, fiber, diode). Whether you're crafting **custom challenge coins** for a unit, **personalized pet ID tags**, **wedding favors**, **keychain charms**, or **collector tokens** — this 21-piece variety pack gives you the freedom to create without limits. Packaged in a premium gift box, it's also an ideal present for the crafter, engraver, or DIY enthusiast in your life.
