I use filler sticks when I have an item that I don't want to subject to solvents of any kind.
The New Hermes (Gravograph) filler stick have a consisteny I prefer over the Lacquer sticks. Softer and easier to work into an incised image.
The drawback of using filler sticks, is that they dry flush with the surface of an item. That means the filled area is subject to getting dirty, as opposed to enamel-filled images, where the paint dries slightly convex, thereby avoiding direct contact with fingers or anything that may soil the image.
To touch-up an image, colored with a filler stick, requires digging out some of the old fill.
To touch-up an image, colored with enamel, simply add more paint and clean.
