12 Pcs 304 Stainless Steel Metal Business Card Blank Laser Engraving, 0.5mm

These are obviously not cheap but worth every penny. The .8mm feel hefty and strong and are protected and polished on each side. They looked beautiful when engraved. One card warped slightly after a long hot engrave with a 20w fiber laser. I am still new to this so I think it was my fault and it was only a slight lift. The .8mm are thick enough that I could bend it back to shape and it looked great . I am so pleased with these, I just wish they were cheaper in bulk.

hopefully I remember to turn these into custom business cards

Very Strong, only slightly flexible. Definitely high quality stainless steel comes with a protective plastic coating that you can peel off, I assume for anti scratch purposes.

For my first attempt at CO2 laser stainless engraving these did OK. I coated them with black tempera paint as a coating. They did warp slightly under the heat so I'd stick with this thickness or heavier. Minus one star for sharp edges - these really need to be dressed down with a file before use.

These cards engrave very well. This is a photo of the first test. A little off center and slightly over burned, but not bad for guessing at the settings. The people who complain that they aren't magnetic simply have no knowledge of metallurgy. The description clearly states that the cards are "304 Stainless", which is not magnetic, nor is 316. If the cards were 430 or 434 stainless, they would be magnetic. It's the same reason some stainless refrigerator doors are magnetic and some are not.

Sturdy, and as described. I cannot wait to get my cards made.

These cards are nickel plated copper. Not as strong as steel and not magnetic. Bought for chemical etching but they won't work for my process. The description is a LIE!

Perfect for me, I bought these to store passwords in my son’s safe in case I get locked out of my password generator, bank, or anything else. My first try to etch the metal wasn’t working well. I had not noticed that there are plastic coverings on the cards that need to be removed print to etching. (No insults, please!) Once I figured that all out, the process went well, and I’m very pleased with the result.

Muy bien viene protegido para evitar rayaduras en las caras

NOTES: 1. Comes with a white plastic coating that you have to peel off. Description doesn't mention this. Only one of the photos in the listing gives you a glimpse of this. And you don't notice (the photo) until you've recieved the goods and wonder why there is a white film on one side. 2. If you're manually stamping words, make sure you place something hard underneath, like a metal plate. I used a crowbar (because that's all I had). My first couple of words I used a block of wood and the words aren't really ledgible. Once I had the crowbar in place the letters came up sharp. 3. Had to hammer the card from time to time during 2. as the card gets out of shape. 4. I used this for my 24word seed phrase. I used 3mm stamps which fitted all 24 words with an evenly spaced gap between. Overall, I'm happy with it, as it is fit for purpose.

財布のカード割れ防止用に購入。 簡単に折れ曲がったりしないので目的は果たしているのですが枚数が多くて知人に配りまくりました。 ステンレスなのでちょっと財布が重くなりますが理解しているなら良い商品。

I like they are thick, they feel thicker than under 1mm, they feel heavy. I have now got my fiber laser 30w and i will test the metal cards and I will give an update review soon with pictures and video.

The cards are slim however you can get easily cut due to the sharp edges
