Recycled polyester fill insert included. All pillows have a nylon zipper closure, with the alexandra ferguson logo embroidered on the center back bottom. The felt that used is made from 100 percent post consumer recycled water bottles. So, you drink water, throw the empty bottle in the recycling bin. Then they are melted down and turned them into this beautiful, really high quality soft felt that I then use to make pillows. The linen used is hand dyed 100% Linen.
