Design Files
(there are 2 types of file: .eps is the vector design file, you can open using InkScape to edit if needed; .pdf is what i converted into A4 size pdf file, incase you need to print using regular printer on papers, and cut by hand. Designs have been scaled to size, so no additional processes needed, just print and cut.)
