I am interested in the 48" Casper Cloaking Technology PF001-801 film, my question is the costs on the page are in US dollars? And if that cost is per m2 or per roll?

Yes, the pricing on our website is shown per linear foot, for each 12" of film length. Casper is available in 2 different widths, 48 and 56" All you have to do is add the linear footage you need and add it to the cart. You will then see the total for film, shipping etc.
