Okay, I should’ve check it out at their website before saying dumb things, but here’s what I learned:
“Normal” (as in not limited) editions are made of resin, most limited editions (like Shiki Oriori, Realo models, and the Kyoyasai as well) are made of PMMA (polymethyl methacrylate). Since I only have LE’s, this one will be no different from my other pens.
I don’t think they’re from the original release. If they were they would’ve been around before the re-release on other platforms, and they would be more expensive. I think the color difference is deliberate to help identify new and used pens of the same model. They might have been bought then tested, and after the customer returned it to the store they began to sell it again, this time at a lower price because they were inked once.
