HC CollectionPillow Cases - Set of 2 King Size Pillowcases, 20" x 40", Microfiber Pillowcase Pack -Navy

Is there even an "Egyptian" polyester/microfiber? (facetious) There is no 1500 TC POLYESTER, right? Cotton is TC, right? Deceptive advertising!

I have standard pillows. Do I get the twin or full size pillowcases? This is confusing.

Why does this item say it’s 1500 Egyptian thread count and looking at my label it says microfiber?

Are the colors in these 1500 pillow cases comprable with the 1800 series sheets ?
