Very cool

This pillowcase is awesome. It stays cool if you get warm you turn it over. It’s cold on the other side. It’s silky but not slippery. Highly recommend these their

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.
