Blank map of Finland
All 18 regions, unlabeled and unfilled. The SVG prints at any size without going fuzzy and opens in any editor. It comes out taller than it is wide, so it prints upright.
What you are printing
A conic projection centered on Finland, so the regions keep their shapes instead of leaning the way they do on a world map.
Every region is a separate shape, so a vector editor can select and fill one without touching the ones around it. Names are in the file as titles rather than as drawn text, which is what keeps the printed sheet blank.
Every region on it
The map page lists all 18 regions by name, and colors them in the browser if you would rather not print anything.
