Stickers seem like a bad idea, did you consider vinyl instead? Even thin plastic tokens would be more reusable and less likely to damage the tiles.

On the page it says there will be 8 extra hexs for pledging in first 48. When you pledge it says you qualify for the 10 bonus hexs. Is that correct? Also, is that 10 2-sided, or 5 2-sided (10 total minimaps).

I have the magnetic ones and use them all the time. Are these the same size?
