Good quality pillowcase for cooling and Skin Care during sleep
Color: 02 - Beige, Size: Queen (20" x 30")
I bought this pillow case specifically for cooling while sleeping during the summer. It works pretty well and also replaces my satin pillowcase used to keep my skin in hair intact. I can recommend this pillowcase if you're looking for cooling and sleekness during sleep.

Very slippery
Color: 01 - White, Size: Queen (20" x 30")
UPDATE: the sellers saw my poor review, reached out immediately, and made things right. Excellent customer service!
I hate this thing. It’s sort of slimy and the pillow case slides all around over your pillow. Would not buy again.
