Celestial Silk is a woman-owned small business creating silk self-case accessories like pillow cases, face masks, and scrunchies. And the brand gives back, donating 10% of all proceeds to charity, and donating pillowcases to chemotherapy patients and lower-income women.

Promising review: “I LOVE THIS PILLOWCASE. It is so soft and comfortable. I don’t wake up with tangled hair, my skin is soft, I sleep like a rock. It stays cool at night (no cold side/hot side of the pillow) and I drift to sleep so easily. It’s like sleeping on a cloud. Eventually I’ll get a few more for all of my pillows.” —sango
