Ok people a little update.
There seems to be some miscommunication with the manufacturer. The "error cubes" had been reused it seems. Some of these "new" ones are imperfectly redone. They had used the old ethereum logo, so they had to laser over the design to remove the lower part of the old logo. If you look very closely sometimes you can see the rework:

The lines on these are usually a bit more blurry as well. This isn't most of them, but I figured I'd ask the communities opinion on this one. Should I keep these in "circulation"? Not sure if anyone would've even noticed, but I've been looking so closely at so many of these... ugh. I might be too much of a perfectionist.
After printing the COAs I learned I had made everything too small. Redoing the whole thing to be bigger (without making everything blurry) was pretty much starting over. Knowing exactly what I was going for sped things up, but still pushes stuff back.
Getting these in the mail first thing Monday morning seems the most likely. I'll be working on these until late tonight for sure, but I don't think I can get these in the mail tomorrow.
This whole thing has been one learning experience after another. Everything takes more work, takes longer and is more complicated than expected, as a rule I've noticed. I am beyond grateful for everyone's patience.
All my time these past few days has been spent on these little beauties, and I don't expect this weekend to be different except Sunday morning

They'll be released into the wild soon!
