Army Painter Speedpaint Sets
Speedpaints are one-coat paints: shade, highlight and base colour in a single application. The 2.0 sets scale from a 10-colour starter to the 90-colour Complete set - but they don't nest perfectly (Mega skips a few Most Wanted colours), so check the exact contents below before assuming bigger includes smaller.
