This product is advertised as a 20x20 inch Pillow Cover. It is actually smaller and measures out at 19x18.5 inches and the insert is too large for the pillow cover. I exchanged it for another and the same problem occurred, and on top of that, customer service did not respond to the issue and I had to pay the shipping costs for a refund/return of the product. Disappointed in both the product and the customer service.
