300TC 100% Cotton 6-Piece Sheet Set

I don’t understand how these are 6 pieces. Nothing in the description explains the six pieces. Are there four pillowcases and a flat sheet and a fitted sheet?

From the Feature list:
Each set includes four pillowcases for added elegance and convenience

So, each set is a flat and fitted sheet, and 4 pillowcases. I’m still deciding if I want to pull the trigger on this one.
