Snuggle up to a great pillow cover
Size: 18" x 18" (Pack of 2), Color: 01-off White
These pillow covers are exactly as described. Very fluffy and cozy. They perfectly fit my 18” pillow forms. Easy to assemble and a quality almost invisible zipper holds it together. They look great as accents on my bed and are very cuddly. I washed them first and they looked great after dryer. Excellent value! Don’t forget they need an insert, this is just the cover!

Solid Pillow Covers + Blanket!
Size: 18" x 18" (Pack of 2), Color: 08-linen, Size: 18" x 18" (Pack of 2), Color: 08-linen
These pillow covers are a great value for the price and the quality feels solid. The soft gray-brown color blends nicely with my bedding and pairs well with the blanket in the same pattern. The ribbed striped design gives them a modern, textured look that would be perfect on a couch or accent chair. On my bed, I think they need to be paired with additional pillows to really stand out, but the size is generous and they are comfortable. Overall, they are stylish, affordable, and well-made.
