I ask that all backers outside of the United States please add $5 to their donation to cover shipping costs. This can be simply done through the contribution dialogue after clicking the "Back this Project" button.
Sorry about any confusion, the ten dollar level was hard to phrase succinctly. At this level you get ONE 9x12 sheet of paper with all FOUR castles printed on it, side by side with their titles underneath (similar to the header image for the project).
Don't see the answer to your question? Ask the project creator directly.
