This listing is for the set of two pillows. Excellent like new condition. These were purchased and then we went a different route with design. With the insert they are a little over 19 inches per side so I believe the 20 x20 was purchased. Our printed pillows are created with the newest eco-friendly technology to reflect the detail and uniqueness of archival textiles while being durable for modern living. Digitally printed onto our signature cotton/linen blend fabric. DETAILS: Front: Libeco 49% Cotton, 51% Linen Blend, Printed Back: Libeco 100% Natural Flax Linen Closure: Exposed zipper with a gold pull Made In: USA Oversized Feather/Down insert included Our fabrics are OEKO-TEX Standard 100 certified.
