These square box corner throw pillows each measure 18x18. The filling is included and is comprised of 95% duck feather and 5% duck down. I have 8 pillows in total: 2 are chocolate colored, 2 are orange, 2 are beige and 2 are teal. Only 4 are pictured to show colors. The pillows are in brand new condition having only been used for decorative purposes to custom match two paintings with similar colors. Each pillow is $60. When emailing with interest, please include which colors you would like as I am willing to split the set.
