【Quality Fabrics】NUTRO CHILL cordless roller blinds are made of a new blackout fabric of 100% polyester, featuring a compilation that resembles a linen feel, and a variety of color choices can be adapted to different styles. The back side of roller window shades has a white blackout heat insulation layer, which can achieve 100% blackout, block UV rays and reduce external noise, which can provide you with a better quality rest environment. 【New Design】The cordless design is more suitable for families with children and pets. Snap-on installation is easier and faster, the upper beam of aluminum blackout cordless roller blinds has a cover shell to completely block the light from the gap between the roller blind and the wall, and the upper and lower beams are wrapped with the same fabric to better fit the style of the room. 【Free Stop & 38 mm Roll Tube】The window blinds cordless have a built-in spring system, so all you have to do is pull up or down to stop in any position you want.
