Satin pillowcases
Size: Standard (20" X 26"), Color: 09 - Ivory, Number of Items: 2, Size: Standard (20" X 26"), Color: 09 - Ivory, Number of Items: 2
These pillowcases are honestly a great purchase. They feel incredibly smooth and soft and I noticed a real difference in both my hair and skin! my hair is less frizzy in the morning, and my skin feels softer.
The quality is excellent for the price, and they’ve held up well after several washes without losing their softness or color. They also feel cool and comfortable throughout the night, which is a nice bonus.
Overall, I’m really happy with this purchase and would definitely recommend them to anyone looking to upgrade their sleep experience!

Great for my frizzy hair
Size: Queen (20" X 30"), Color: 06 - Black, Number of Items: 2
I got these because I really wanted something to helps tame my frizzy hair but also help with my skin. I have very sensitive skin and my break outs have reduced so much! They fit my standard pillows without an issues. The color never fades, they wash and dry well. The quality is on point. Worth it.

Cute, soft, and warm!
Color: Cow, Size: Throw(50"x60")
Super soft and super warm! This nice and thick blanket feels so nice when you wrap yourself up in it; and it’s just big enough to do exactly that!
I’ve washed it a few times and it comes out even softer and fluffier than when I put it in the washer; and no issues with losing fluff or thinning/tears.
I love the cow pattern too!
