2ml sample of Private Reserve Back in Black fountain pen ink, in a labeled plastic vial. 

This is a limited edition color, a black ink with added silver shimmer!

Due to the amount of particulate in this ink used to achieve the sparking look, you may experience restricted ink flow in some of your pens. We recommend shaking the ink thoroughly before filling and gently rolling the pen in your hands often to keep the shimmer effect consistent. This will also help prevent clogging. You will also want to be diligent about cleaning and maintaining your pen when using this ink.
