Bertram’s Inkwell makes every effort to represent our products accurately online. However, actual ink colors may differ slightly from those shown on your screen due to device settings, display variations, and lighting conditions. Fountain Pen Ink colors can also vary based on your pen’s nib size and the paper you use.

How to Choose the Right Fountain Pen Ink

Choose bottled fountain pen ink if you want the widest color selection and a more refillable writing experience. Bottled ink works with compatible fountain pens using a converter, piston filling system, or other bottle-fill mechanism.

Choose ink cartridges if you want a simple, convenient refill option with less setup and easier travel. Cartridges are a good choice for everyday writing, school, work, and anyone who wants a faster refill process.

Choose 10-piece ink sets if you want to explore multiple colors, give ink as a gift, or build a more expressive writing collection. Ink sets are especially useful for fountain pen users who enjoy changing colors for journaling, letters, creative writing, or collecting.

Choose fountain pen flush when you want to clean a fountain pen between ink changes or help remove old ink buildup. Pen flush is a useful care product for fountain pen users who change colors often or want to maintain smooth ink flow.
