I love satin pillow cases and never travel without them. They are very hard to find and usually cost a lot more than these. I must admit that I was a bit unsure as to what they would actually look like when I got them because the picture looks like they might not cover a standard pillow. I was pleasantly surprised when they arrived and actually fit my standard pillow like a glove. They do zip at the end which gives the pillow a dressier look than the opened end. I would definitely purchase these again. Because they come in a pack of four which is unheard of, I was able to cover the pillows in my teenage daughters room which really gave the bed a more dramatic diva look. She loves them as much as I do.
