COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
