Love the Pentel Sparkle Pop? These new gel pens are sure to dazzle you! The glittery iridescent ink in Krazy Pop pens adds a dazzling, dual-color sparkle effect. Ink changes color on different colored papers and depending on the angle the writing is viewed. Smooth, metallic gel ink flows out of a 1.0mm metal tip, and extra-long balanced barrel allows for effortless writing and control.
