Blank Brass Challenge Coin Laser Engraving Coins Blanks 40 mm with Acrylic Protection Box for DIY Crafts Birthday Travel Commemorative Collection (10pcs Brass)

Muy muy recomendables, si son de laton, he comprado otras y solo tienen el baño pero por dentro es acero, si las super recomiendo.

These were surprisingly good for the price. Quality of the finish across the whole batch was excellent. I make tokens and challenge coins for promotional materials for businesses and these have been working well with my IR laser for engraving.

These coins are solid brass! At first, I thought I might be getting a knockoff claiming to be brass, but after cleaning them up after the fiber engraving, they came out nice and clean. I have a couple of others I made, but they are not appropriate for showing due to the words on them. These are certainly worth the money and feel and look great.

These are very nice. Much thicker than others I have bought. Also has a flat polished surface rather than the textured on others. Highly recommended. Cost is higher, but worth it. Used for fiber laser engraving

Coins were mainly consistent with quality, all having a nice, initial shine to them. The are pretty accurate when it comes to coin size, shape, and stamp. They work well with laser engraving and have nice housings to place the finished coin in. Only issue I ran into was one of the coins had soft, almost dent-like edge to it (more noticeable in real life). For almost paying 3 dollars a coin, I would expect this to not be an occurrence, but overall, good coin.
