My go-to calculator has been a Casio fx-260solar. It's not a high-end scientific, but it does the basics well. It's also nice and small, turns on quickly, and runs in lower light than my old TI-36X Solar. I just got a new-in-package one on eBay for use in my basement workshop.Turns out, though, that this new one is slightly different than the other one. It's not the completely new redesign that Casio did that has the weird patterned/textured body. It's just very slightly different. The length, width, and thickness are all slightly smaller. The cover is a poor and too tight fit. The original is made in China, the new one in Malaysia. But the worst offense is that the keys are the awful soft keys. Ugh! So awful that I can't use it. I love using the original, though.So I was wondering if Casio would have actually spent time doing this slight (and worse!) redesign. Why make new molds for the plastic? Why go from China to Mayalsia? (pre-pandemic). Or if this might be a knockoff? (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link)
I find it odd that my good old calc has no patents listed on the back, but the one that I suspect is a knockoff has all sorts of patents listed. [...]

ps: reading other materials trying to understand this matter...https://www.schwabe.com/newsroom-publications-gilbert-p-hyatt-v-andrew-hirsfeld-appeal-nos-2019-2390-2391-2392-2019-1038-1039-1049-1070-fed-cir-june-1-2021https://www.quinnemanuel.com/the-firm/publications/lead-article-snooze-think-again-prosecution-laches-and-why-applicants-and-litigants-should-beware/
While looking around for more clues or an answer to this mystery, I stumbled upon this image which shows the same two variants as in the OP: https://casio.ledudu.com/images/calculs/casio/machines/zoom/fx260SolarX2.jpg found on https://casio.ledudu.com/pockets.asp?type=927&lg=eng

The good news is you got a more accurate one. The bad news is, this mystery continues even more... according to the table linked above, the only known calculators to give that result are 3 Casios (not the same model) and 2 Radio Shacks.
I prefer the Solar II Always wanted to get a custom EEVblog branded Casio FX-260 but they ignored my requests
What I see from the pictures - smaller display, smaller PCB, smaller case - cheaper to produce. Don't forget that if you save 10 cents on million batch device you will earn USD100k. Next reason can be supply chain, worn off tools for plastic (even steel one need the maintenance), new calculator chip etc. Don't forget Casio is Japanese firm - they like to improve.
