IKEA pleated blinds (Barton upon Irwell M30)

I have 4 of these blinds (3 unopened, 1 opened but unused). It says 100% polyester. They are fabric but paper like. We used some as a temporary solution whilst we were waiting for blinds and they were good for having something up at the window. Quite transparent when the light is on or the sun is shining but ok at this time of year. The dimensions are on the photos. ☺️
