Extremely poor quality, maybe 100 Thread Count? No material composition is to be found on the duvet cover or pillowcases or the package. Was not properly stitched and came stained, but Wayfair still requires me to spend £5 on a return per item because their customer service is the worst. I ordered 2 sets and now I need to pay £10 for a return, ridiculous! They referred my case to Resolution Management which requires a million photos to be sent to them, and all of that for prepaid return labels
