Received my sheet set one day last week and opened it up today. No label, so I'm not entirely sure how anyone could identify them as Cali Kings from outside the package. But they are marked on the inside labels as C King, so I'm ok with it. They are very thin, but they do feel like they will be nice to sleep on. But the main thing that I noticed about them is that they smell absolutely AWFUL. There is a terrible chemical smell coming from them even after washing them twice and drying them. They are currently on a third wash. I don't know what I am going to do if the smell does not come out - I certainly can't sleep on sheets that smell like these do. Very disappointed so far.
