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!

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

I bought it again!
Size: King (20" X 36"), Color: 07 - Pink - Zipper, Number of Items: 2
This is the 5th time I have bought this pillowcase. It's exactly what you would want - zipper that works, great feel to the satin, color stays constant, and it fits nicely. Also washes well - just throw it in the washer with everything else!

These sheets are very nice and very slick lol. It’s kinda hard to keep things in place but I like them. Reminds me of that song slipsliding away.😂
