Used for just under 4 months during the summer on a child's room window. I had them on an east-facing window, and they were effective at blocking out the morning sun. I'm selling these because I bought a different color for a room change. The back side is the same color. Purchased from AIFY on Yahoo! Shopping. Color: Light blue A gentle color, like a muted blue or a pale blue-gray. The color in the last image is the closest match. 100 x 110 (cm), set of 2 Curtain hooks are also included. Home cleaned. - Color: Light blue - Features: Complete blackout, heat insulation, soundproofing, shape retention - Blackout rate: 100%
