12 Pieces 304 Stainless Steel Metal Business Cards Blank Steel Laser Engraving Stainless Cards for House Office Customer DIY Gift Plate, 86 x 54 mm(0.4 mm)

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

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.

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.

These are NOT stainless steel. Steel is a ferrous metal and is therefore magnetic. These are NOT magnetic therefore they are NOT stainless steel. Bought these for * scraping adhesive (I sharpened the edges with a diamond grit whetstone) * making a “forever business card” (which I have yet to do) * cutting and mixing JB Weld Steelstick epoxy to beef up bicycle handlebars so my tactical flashlight mount would stop shifting each time I hit a bump (it worked and that was why I sharpened the edges) Would buy again as these were a good value for my money but keep in mind that these are NOT stainless steel as is claimed

I used these with a simple stamper to permanently store the seed phrases for my crypto wallets. The 12 pack price made it so I can affordably store multiple wallets, and I can store half of my seeds in one location and the other half in another location. As a suggestion, if these are warping from your stamping rods, you just need to get a stamping bench block. After I got that, I didn't get any warping.

These are very solid at .5mm of stainless and in that regard very pleased. That is offset substantially by the cut quality, it seems obvious that these are stamped out on a press which isn't necessarily a bad thing but the stamp is probably not sharp enough or to wallowed out to make clean blanks. The blanks have bends and creases near the corners almost certainly from the cutting out process. This is very noticeable in the types of products these blanks are used to create. I do like that the blanks come with protective plastic film on both sides. It is hard to peel but that's preferable to easily peeled tape that comes off in shipping and handling. The protective film itself isn't in very good shape, it seems like these blanks lead a very hard life before getting to your door. If you just want blanks to do some fun stuff for yourself or friends these are probably a reasonable purchase, if you're looking for professional quality blanks to craft on and sell I would keep looking.

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.

Sure they come with a plastic coating, but they're so poorly packaged that they're scratched up anyway. Useless as laser blanks. Buy from someone better.

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
