These are the best token markers I've found for Pathfinder 2 on Roll20. The strong colors combined with the heavy outlines make them show up real well against the tokens, and the selection is good without being overwhelmingly large. My players also found them to be a lot clearer.

(Deleted my one beef with the product because I was made aware that Roll20 can do that on its own, so there's no need to have the markers do that. Today I learned.)
