Product is good. Could not use it for my laser.

The ComMarker 20 Pcs Copper Blank Challenge Coin set is more than just a bundle of metal—it’s a canvas for memory, meaning, and meticulous design. Whether you're engraving for ceremony, storytelling, or symbolic keepsakes, these coins deliver. Highlights: Premium Feel: Each coin is solid, with a satisfying weight and a rich copper tone that engraves beautifully. The 3mm thickness gives it a substantial, heirloom-like presence. Threaded Edges: The subtle texture adds a refined touch, making each piece feel finished even before engraving. Protective Acrylic Cases: Every coin arrives in its own clear box—perfect for gifting, storing, or showcasing without scratches or tarnish. Engraving-Ready: Smooth surfaces on both sides make these ideal for laser engraving, etching, or stamping. They take detail well and polish up with a brilliant luster. Versatile Use: From wedding favors to travel mementos, spiritual tokens to DIY jewelry, these coins adapt to your vision. Considerations: Real copper means they may patina over time—some see that as charm, others may want to seal or buff them. The packaging is utilitarian, not luxurious—but the coins themselves are the stars. Final Thoughts: These blanks are a dream for creators who value symbolism and craftsmanship. Whether you're engraving Adinkra symbols, Hebrew phrases, or personal poetry, they hold space for meaning. I’ve used them to mark spiritual milestones and poetic reflections—and they’ve become part of my ritual of remembrance.

El producto no es cobre auténtico como indica en la descripción. De hecho, en el propio texto del anuncio aparece una contradicción: primero dice “cobre auténtico”, pero unas líneas más abajo afirma que “estas monedas están hechas de latón puro”. Esto explica por qué no se comportan como cobre real: no se pueden grabar igual, no oscurecen, y la dureza es mucho mayor. Probado con una máquina láser de alta potencia (1064 nm), el cobre puro se marca enseguida, pero estas monedas apenas reaccionan porque no son de cobre. Son monedas de latón con un baño/tinte color cobre, no cobre macizo. Si buscas cobre auténtico para grabado o para trabajos artesanales, este producto no es adecuado

Can't wait to get something done up with these.
