That's strange. The cloth does come folded in a plastic wrap, but it hasn't left any marks on my screen from the folds. If it was that serious, I could always take an iron to it, I guess, but it's a microfiber cloth, not plastic that will mark your screen. Also, no sharp edges at all - again, it's microfiber material. The edges do look like they were cut with scissors in some spots, but you're not cutting your fingers or scratching the glass. When I take it off the keyboard, I loosely fold it to put it away.
One thing, I wish the other Uppercase cloth was dark like the Kuzy cloths. The Uppercase cloths will look dingy faster because of their color (dull beige grey) even if they are clean.
The Kuzy cloths are great cleaning cloths in general. I've been using one for my iPad Pro screen. Like I said before, the Kuzy cloths are a little thinner than the Uppercase cloths.
I may look for a darker cloth similar to the Uppercase cloth for my next purchase. That would be perfect.
