40mm (just over 1 1/2″) suction cup with screw (M4*6mm) with separate ridged nut, standard cup, sucker, suckers, plain, clear vinyl PVC suction cup with screw

Very good grip when attaching to glass and the thread on back made it easy for me to attach to the thing I wanted to hold… I have been using them in the car to hold sun shades up to shade the kids (replacing the original suckers which were of a much lower quality). They’ve been on the car window constantly for a couple of months without falling off at all. After two months the plastic seems just the same as when I put it in, so it seems to be resistant to heat / cold / UV.

Perfect, just what I wanted, I’m crazy and want a ‘living’ wall of plants in my bathroom, so I put these through some plastic cups, filled with water and put live moss balls in them, naturally. They hold really well and to be fair I think they are worth the money. Excellent.
