The file 'Laser Cut Portal Cards' is (zip,ai) file type, size is 13.7MB.
These playing cards were made using Valve's online comic "Lab Rat" http://www.thinkwithportals.com/comic/ and thus can be used only for your own personal set, not sold or redistributed for profit.
I printed the set through http://www.printerstudio.com but you could use similar custom card-making websites or just print off the cards yourself on your own printer (if printing yourself make sure to use a thick enough paper with semi-gloss!)
