I used 175GSM A4 card/ paper so use google to transfer that into whatever your country uses.
The file I used was a mark 3 file that is hard to find now but the creators made the most popular files around and I'm actually going to do a mark 7 with this by taking away those cheek pieces apart from that the mark 3,4,6 and 7 are the same!
Search sharkhead7854 and dubean33 in google to find their files.
