Bought these a couple of months ago.  Crisp still after several washes.  The cotton is ‘thicker’ - good quality.  Important to not let it ‘over dry’ as it is more wrinkly then.  I really like that the flat sheet has a good solid trim as it has not folded over (and thus requiring ironing to flatten it out).  I do iron the top on all my sheets though as I like the way it looks when I fold it over the blanket and bedspread.  This did come with pillow cases (and I iron them but if you take them out at the right time and don’t let them sit in the dryer, and flatten them out, they are pretty good).  Our bed is 18in high and these sheets fit fine.  I really like the elastic that goes all the way around on the fitted sheet.  I usually keep two or three sheet sets in rotation and when I need another set, I will look for those again as they get better with wear in terms of comfort and smoothness.
