Review on 18.5" W X 48" H Cellular Honeycomb Cordless Blackout Shade - BlindsAvenue Gray Sheen 9/16" Single Cell by Josh Boii

The manufacturer sent out this order very quickly, and he offers many custom sizes so you can get an excellent fit on the window. The blinds have a quality look. The small ones I ordered have worked well enough.These are attractive blinds and they go up and down smoothly, and they are indeed "blackout" blinds as advertised. But -- I am reminded of the negative of this type of honeycomb blind-- it's only made of reinforced paper, so it will eventually fall apart and could be damaged by anyone handling it roughly.AND worse yet, one of these two sets of blinds has stopped retracting and now has to be replaced. The larger the blind, the heavier it is, and the quicker it is likely to stop retracting. These honeycomb blinds without strings are NOT workable in a large size-- the window in question is about 5 feet by 5 feet.It's too late for me to return this purchase so I am stuck.
