Color coding is an old-school method that’s a proven way to increase productivity. Colors help organize and prioritize a To Do list—one quick glance tells what task belongs to what category (work, family, appointments, exercise, travel plans, finance, home projects, etc.) and what needs to be done sooner rather than later.

But this set of eight pens isn’t only a tool for efficiency—using them is lots of fun. Journaling, writing thank you notes and gift cards—what can’t be improved by a rainbow assortment of fountain pens? The set includes one each of violet, magenta, purple, turquoise, green, yellow, red, and orange, each with a medium nib.

And we admit it: we had low expectations for plastic fountain pens, but we were far more than “pleasantly surprised”—these pens are impressive. They’re chic (stylish with a sense of fun) but eminently affordable. Most important for a product that is first and foremost a tool to be used every day, they're beautifully engineered: the soft matte barrel is comfortable to hold, the pens are lightweight but anything but plastic-y, and the nib positively glides across the page.

More thoughtful details: an easy-to-follow diagram on the package shows how to install the ink cartridge that is provided with each pen (unscrew, flip, click—how easy is that?); we also offer replacement cartridges for the ink.

Whether you're writing an action plan or ruminating on the day’s events, you’ll find dozens of uses for this colorful enhancement to penmanship.
