"stay sticky" Having only recently acquired them, I'm not in a position to say for sure right now. They adhere tightly, but come off easily. They are returned to the backing they came on when not in use. I suspect making a point of that will lengthen their lifespan. They're not too expensive. If they had to be replaced a ways down the road, it wouldn't be a big deal. I can't exaggerate how convenient they are.
