MS WGO 100pcs laser engraved Metal Business Cards Blanks 3.4x2.1in Thicknes (0.45mm)

I didn't use these for business cards but for reproducing data plates. They worked well, but were not as crisp as the picture I used as a template. That may be the limitations of LaserGRBL however. I used an Atomstack A5 with a 4.5-watt output blue laser at 100% power and 1000mm per minute, one pass.I tried vectorizing the image but printing it as a raster seemed to work out better. After lasering, you have to wash out the image with a soft toothbrush and some water, and maybe a drop of dish detergent to get the paint remains out of the design.The cards have a protective film on one side that you have to remove (before lasering). This is the scratch-free side. You can laser the opposite side as well but since it was not protected, it will have scratches. I don't think this is a big deal since the whole thing is going to end up scratched if you use them as business cards anyway. The good thing about this pack is that you can screw up some since you have a hundred of them. The rounded corners are nice as well. There was minimal blood drawn when working with these.Overall, I am pretty happy with these metal cards. There are plenty of them and are two-sided that can be used (one side for scratch free and the other for additional information). They are perfect for recreating data plates as well.

I bought these to etch business cards for myself and experiment with a few other jobs. They come with a thin plastic film on one side, which is the side I have been etching on.There are two reasons why these are not a perfect product, and for each I removed one star.First, the cards have unfinished edges with lots of scrapes and blemishes on the non-plastic-film side of the card. The material easily scratches and scuffs, showing the metal underneath.Second, a large amount of my cards were bent in the middle to where they would not lay flat on my work surface. My laser has a fixed focal length, and this means that the focus doesn't perfectly match the surface as it scans over the whole card. Id estimate that half are flat and half are not.The etches that worked out look very good. I am using an Atomstack A5 hobby laser.Pro tip: 10mm/s etch at 10% power was more than enough to etch all the way to the bare metal surface of these cards. At 100% power, the surface was scorched and turned black.

The edges are fairly sharp so i wouldnt recommend using these as business cards but ill be using them for recording data so theyre fine for that

This product arrived early each time I order. Cards are broken up into groups of 50 . All cards were in perfect condition and are easy to engrave on. I use them over and over I highly recommend

These come with protective film on one side. However, the other side was scratched on many of the cards. Will not buy again.
