Unlike traditional drawstring designs, Deco Window Spring Roller Blinds use the elasticity of the built-in spring system to control the rise and fall of shade so you can filter out the unwanted light, glare, heat, and UV rays to keep your space cool whilst having enhanced level of blackout inside for privacy. It is very convenient to pull up or down this spring blind and can be stopped at any position you desire. Just pull down to the desired length and stop; it will automatically stop at the leftover position. Gently pull down the blind again to automatically close it without any effort or rolling.

The shade width is for total roller width including hardware, not for fabric width. Fabric is about 1.4 inch less than shade width because there is mounting hardware on each side which takes about 0.7 inch space on both sides. Cleaning Method: You can clean them with a damp cloth or feather duster.
