From the manufacturer:
Creme Liner is an advanced version of traditional creme liner, which can be used wet or dry. It can be applied straight from the container for a concentrated opaque line, or with a tiny bit of water for a more liquid/fluid application. It dries quickly, is streak-resistant, and long-lasting. Not made with harsh solvents or lacquers like some, this formula contains Vitamin E. It provides the most versatility for the artist.
