Love these!
Size: Standard (20" X 26"), Color: 02 - White - Zipper, Number of Items: 2
I like these better than the Blissy mulberry silk pillowcase. They feel smoother and softer and make my hair less frizzy. I've been buying these for years and they hold up great! I just switched to the zipper version instead of the envelope style, and I really like the more modern aesthetic of the hidden zipper. They are nice!

Fitment

Nice pillow cases, good construction and materials. But just a little short length wise. Very tight fit

I bought these because they were recommended by my hairdresser for hair breakage. I love the zipper because the pillow can’t slip out. I will sy these do feel nice against the skin as well.

Feels heavenly
Size: King (20" X 36"), Color: 14 - Lavender - Zipper, Number of Items: 2
Literally just got it in the mail and fell in love. It's so soft and wasn't being harsh with my beard hair. Hopefully no more split ends! (Good hair protection!)
There was no odor to speak of and it fit my pillow perfectly, we got king size, (AKA good compatibility)
