Soft nightcap made of TAKEFU Retail price: 3080 yen It doesn't cause static electricity and doesn't prick, so it's comfortable. I use this as a sleep aid. Especially on days when I'm tired, I feel like the quality of my sleep is different when I wear it deeply, covering my eyes. (Although it's usually off in the morning, lol) For warmth in the cold winter mornings and nights, indoors and outdoors. My husband always wears it when he has a cold. He wears it on cold days even indoors. It's comfortable because it doesn't constrict (it loosens as you wear it). It seems that if the bamboo fiber content is over 70%, you can expect an energy effect almost equivalent to 100%. Please try it, especially on days when you're exhausted or have tired eyes ✳️ - Brand: TAKEFU - Product name: Nightcap - Size: FREE - Material: 70% rayon, 30% cotton Thank you for viewing.
