Roller Sunshade for a Car Sunroof, Three Colours

A glass roof is wonderful until July. This cloth roller shade covers the sunroof opening and cuts the direct light that turns a panoramic roof into a greenhouse by mid-afternoon, then winds back onto its bar when the sky clouds over again. Three colours are sold: grey, black, and beige. Each one is 300 grams. It rolls up small. Fit matters more here than on a windshield shade, because this is cut for particular sunroof openings rather than a universal rectangle, so measure your own opening before ordering instead of assuming it will reach the far edge. There is no motor and no switch anywhere on it. You draw it across by hand, which also means nothing to wire and no fuse to find.
