NATURETY Bedding Fitted Sheet with Deep Pocket,Thicken Printed Fabric Bed Sheets (Navy Blue(Dinosaur), King)

Do they make matching pillowcases?

The description says its deep pockets, how deep is the pocket?

What’s the thread count? Not what it feels like.

Where can i buy the flat and pillow cases for this? What good is the fitted only.. i have the quilt and need the rest. White version is good too!
