2 x Strong Mirror Pads Car Interior Mirror Double Sided Stick On Pads. 2 Pieces Supplied Piece Size: 40mm x 28mm Can be used for other purposes as well Use to fit on your number plates but you may need a few more If your mirror has fallen off the windscreen, unless it is the type that is screwed on or fixed to the car, you will need one of these to fix it back on. This will not work on very heavy electric mirrors. The Best way to fix it back on is to clean the glass with some type of alcohol methylated spirit Brandy, whiskey that type thing, not white spirit. Also make sure the mirror is cleaned also the same way. Then peel back one side of the pad and stick it on the mirror. When the weather is cold outside any sticky pad will not work properly and may fall off. So the best.
