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!

A must have for sensitive skin
Size: Standard (20" X 26"), Color: 20 - Moss, Number of Items: 2
I am now on my second set of these pillowcases, and I can’t recommend them enough. I have extreme skin sensitivities; anything even slightly rough against my face will give me a rash. These are incredibly smooth and have been a total game-changer for my skin. I love them so much that I actually travel with one to put over hotel pillows whenever I’m away from home. The best part? I didn’t want to pay a fortune or deal with "hand-wash only" items. I throw these in the washer and they come out perfectly every time. They maintain their color and don’t lose that elegant sheen.

Fantastic satin pillow cases for the price
Size: Queen (20" X 30"), Color: 02 - Pure White, Number of Items: 2
Edit: I already put five stars in the first place, but I was unfair to these pillow cases in my initial review! I thought they were a little warmer than the natural silk, because I was sleeping on them with acrylic pyjamas on. I have come to realise the pillow cases are not warm. They are truly excellent in every way. I just get sweaty every time I wear acrylic pyjamas! I have already ordered two more sets of these (and have switched to micrfibre pyjamas)! Original review: First off, I want to address a popular misconception. Satin is a weave, not a fibre. So polyester satin is real satin, and it is very common. To all the people saying the makers lied about the fabric, they absolutely did not! I bought these and I bought some inexpensive silk ones at the same time. I have been loving the silk ones and only started using these lately. I'm happy with all of them. These are not silk, and I can feel the difference, but they are a nice, smooth polyester satin. The white colour is indeed a pure white. I machine washed mine and hung them to dry. They did not wrinkle, pick or pill, and they did not change in colour or size. They look fresh and pristine. I measured my pillows and got the right size. They are pretty and neat, they seem to be well sewn and well finished, with no hanging threads. They are very soft to sleep on and did not make my dry, curly hair frizz up. I slept on them without my protective bonnet, so I got the full experience! Honestly, with the smooth, tight weave of the fabric, they may be superior to the real silk in terms of babying my skin and hair. However, they are a little bit warmer. That is fine for now, since the weather is cool. I might just use these while it is cool out and switch to silk in summer, or I might continue to alternate, we will see. Overall, I am happy with my purchase and would buy them again.

Worth the price
Color: 35 - Lavender, Size: King
The best thing about these king-size sheets is the deep pockets—they stay securely in place and fit the mattress perfectly. They wash beautifully, resist wrinkles, and are incredibly soft and comfortable. A great combination of quality, comfort, and convenience.
