How does this have a 5 star rating when the 1 star reviews are horrible and you can't return them? Concerned about not being able to return for refund

I purchased these in 2018- AMAZING! Came back to repurchase and saw a one star review stating first purchase was amazing, second very different and horrible. As far as a seller stating “No returns” that only means it’s something that is not allowed to be accepted as a return (like food or drink). If you call Amazon and explain situation- They WILL give you a refund!!

what size are the towels when folded, 4 x 8.5?

More like 4 1/2 × 8.00 inches folded

Are these still manufactured in China?

The box of towels I just received (Nov 2020) says made in Turkey. Not sure where it was made when this question was asked.

Is the texture too course to use as dinner napkins for wedding?

Not at all, I'd say these are an impressive thickness. They don't feel cheap or look like a bathroom paper towel. They don't feel coarse to me in that way. I'd say one seems to be as thick as a dinner napkin made of cloth but not silky like one. It doesn't feel rough to me.
