The Think Transit Green Line Fountain Pen features a colorful, appealing pen with a darker barrel and lighter matching cap. What is it you THINK about? THINK about where you'd like to go, places you'd like to see, people you would like to meet. THINK about your accomplishments, goals, and desires. THINK about who you want to be. Just remember to write it down. Think pens are of excellent quality and a perfect fashion pen! Fountain pens are enhanced with a medium steel nib and cartridge/converter fill. A metal clip and band make this pen more eye.
