I purchased one of these off of eBay for my old X after my actual Apple silicon case failed after a year and a half. Looked exactly the same but when I installed the two bottom corners split a little (maybe they were factory seconds) I used it all the way up until trading for my Pro Max though. I do love the Apple silicon cases and have the pine green one on this Pro Max.
Edit: Sorry I see this if from 10/28. I’m getting old...
