Black carpet adhesive (same principle as the Gecko carpet cheaper) very convenient for the dashboard of a car. Mat 14 cm long by 8 cm wide. I put my glasses or my phone. I put it on the flat dashboard and it does not move. I did not positioned vertically on the dashboard like the pictures. I'm falling and all the dust that is stuck on it because of sticky plastic. I cleaned with water and a dish brush and I recovered as new. Think where you put the adhesive carpet before ordering. I advise you to put it on the dish. Very good value for this small adhesive pads, I recommend it.
