THE NEW 12
I call these Staedtler Triplus® fineliner pens the “Perfect 12” because they are easy to carry around, write beautifully in my sketchbook and, most importantly, they match my recommendations for the 12 colors to have in the Color Explorers Classroom. As a bonus – they come with a very cool triangular pen case.

These are often on sale in office supply and art materials stores. Online, I found the best price is on Amazon.
