Transparent no logo static stick decals?

you know when you get an oil change and they stick that decal on your windshield with the next service time? or you peel it off the screen of some of your electronic products? i kept mine on my mp3 player since it keeps the screen clean, but it isn’t transparent.

where can i get a single large sheets of those cheap? i want to cover some of my stuff: monitor, cellphone window, etc. some of the places i looked required large purchases.

Look on ebay. Buying stuff that generally isn’t sold in consumer quantities often involves buying a load and selling what you don’t use on ebay.
