Love Them!
Size: 18" x 18" (Pack of 2), Color: 05-light Purple
I love these pillow covers. They're so soft and comfy but the off white is more of a bright white.

Great quality for price! Worth it!
Size: 18" x 18" (Pack of 2), Color: 01-off White
I’m skeptical of Amazon sometimes because the picture usually looks way better than the product. But here are great! The material doesn’t look cheap, the zipper looks quality, overall looks very quality! I have not washed them yet but if anything changes I'm will update this review. Definitely worth the money. I don’t leave many reviews but I thought this was was worthy!
