This is a set of two standard size satin pillow cases by FabricMCC. The color of these pillow cases are true white. There is satin on both sides of these standard size pillow cases. There is a zipper on the end to keep the pillows inside of these cases. The zipper is coved with satin so it is not irritating to your skin. The material is so nice feeling and soft and cool on the skin. I have had no issues with being hot or sweating with these. These wash well in the machines. These came made well with no loose threads or holes in the fabric or at the seams. I had to order more as my husband likes these also.
