The fine tip works well for little details as well as larger drawings, words, etc, and the colors are so vibrant that you do not need to add an extra coat. And the best part is that they work on every type of surface - metal, glass, wood, rubber, plastic, and even wet surfaces - the list is endless.
I purchased mine at my local Napa Auto Parts store, but they are available at many other hardware stores as well as several online sites (including Amazon.com, my favorite place to shop).
I used my Super Met-al Marker on this journal page, and as you can see, it worked perfectly. The color really pops against the background, and I only used one coat! Yay for Super Met-al Markers!
Here's the product link on Amazon.com if you are interested in trying them for yourself.
