I would recommend them. ### ⭐⭐⭐⭐⭐ Review *by L***E on 1 February 2025* Super qualité ! Maintenant reste à les faire passer sous le laser de la graveuse. ### ⭐ Review *by C***N on 14 November 2025* 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 ## Frequently Bought Together - ComMarker 20 Pcs Brass Blank Challenge Coin,2.2mm Thickness Threaded Edged 40 mm Engraving Blanks Coins,Acrylic Protection Box for DIY Crafts Engraving Travel Commemorative Collection Supplies - SINBRLAI 10 Pcs Blank Challenge Coin, Engraving Blanks Coins, Solid Brass/Zinc Alloy Silver Plated 40mm Diameter with Acrylic Protection Box Pattern for DIY Crafts Engraving - 20 Pieces Blank Challenge Coin Threaded Edged 40 mm with Acrylic Protection Box Laser Engravable Pattern for DIY Crafts Engraving Travel Birthday Commemorative Collection Supplies (Yellow) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/612615619-20-pcs-brass-blank-challenge-coin-threaded-edged-40-mm](https://www.desertcart.pl/products/612615619-20-pcs-brass-blank-challenge-coin-threaded-edged-40-mm) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
