Purchased from Nissen in February 2026. I intended to use this as a sofa cover, but the size didn't fit, so I'm selling it. I only put it on the sofa once, so it's practically unused. This turquoise blue duvet cover is made of 100% cotton, and the reverse side is warm flannel, providing comfortable sleep. - Size: Double - Color: Turquoise Blue - Material: Front = 100% Cotton, Middle = 100% Polyester, Back = 100% Polyester - Features: Warm flannel on the reverse side Machine washable, use a net.
