I just received the white King Size Duvet cover as part of the Tried & True program. It is okay. It is very thin, and I do not see how it would be considered reversible. One side does have a tufted pattern, but the other side is like a plain sheet. 

It seems to fit my King-sized bed fine, and it came with 2 king sized pillow shams. That is not useful for me because I only use standard size pillows. No fault on the supplier regarding the size as most king-sized bed sets are like that. The shams are the envelope type and I assume king sized pillows will fit in those nicely. The duvet cover itself has a zipper to insert the comforter in. Even though it is a very thin material it didn't really show any color through it when I looked at it with a blue towel inside. And the corner ties are strips of ribbon sewn into the corners onside the duvet cover.
