The package includes: 4 sets of quote pillowcases, no inserts or fillers. The pattern is only on the front and no printing on the back. (The pillowcase can help you quickly replace the decorations. It is also a super cute gift for your relatives and friends.) Size and material: This pillowcase fits 18x18 inch inserts. Please note: All our pillowcases are made to ensure a fit. Each listing size refers to the size of the pillow, not the size of the pillowcase. To ensure proper fit, we make all pillowcases slightly smaller than the insert size (about 0.5" smaller). Made of 100% polyester, it is soft and skin-friendly, does not fade or wear, and can be used outdoors. Easy to wear: The color-coordinated hidden zipper closure brings an elegant appearance, and it is very easy to stuff pillows/fillers into this pillowcase. Washing tips: machine wash with cold water alone, only gently cycle, do not bleach.
