However, crystals are not ice, but formed naturally inside hot spring. When the hot spring’s temperature and pressure becomes low, the silicic acid inside would slowly crystalize itself.

Color is off, feels decent
Color: 07-beige, Size: 20" X 26" (Pack of 2)
Feels nice and very cooling to the touch. Although you can tell it definitely isn't cotton. I ordered the color beige but it is much more of a cream color.

Great case
Color: 03-dark Grey, Size: 20" X 26" (Pack of 2)
Love these pillow cases! FYI: 20" X 26" are PERFECT for supposed "queen size" feather pillows. 20" x 30" ones are too big and allow the feather pillow to flatten out too much. There is a bit of stretch to the cases. The "cool side" of the pillow case IS NOTICEABLY COOLER than the other side. Good zipper.
