Costco duvet covers, are they good?

[mosaica]

Hi, Costco online have some superking size 400 tc duvet covers in plain white and ivory. The price is very good for the specs, but it is tricky as I have not seen them in the flesh. I don't have a Costco card so I cannot check in the shops.

Are they good quality and non-shiny? Thanks.

I haven't had their duvet covers, but have had their bedsheets.

Not cheap - and we only don't use them anymore as they got stained (!).

But I do find all their products good quality.
