Not premium at all
Unfortuantely, I have received a fitted sheet that was not according to the quality that I expected. The cotton was only 300 thread, the stiching was sloppy, the packaging was from a random tailor like you could find it in Satwa. The "edges" of the fittted sheet are not round, so they stick out when you pull it over your mattress. I would not order from them again and would not recommend them.
