I only use all cotton bedding, and when I can afford to get it, organic cotton. With my insane allergies, it's a must. These pillow cases arrived nicely packaged. They are true to size, and had no imperfections upon arrival. The seams were done well, and they had no odor.  I washed them upon arrival,  and they washed beautifully.  Seams held up, no pillow ingredients. Just a solo pair of pillow cases. I am really loving them. I did receive these to test but all opinions are honest and my own.
