Private Reserve Infinity vs Rich Bright Colours Fountain Pen Ink
Choosing fountain pen inks often means balancing a specific writing feature against a straightforward color and price preference. Private Reserve Infinity and Rich Bright Colours point in different directions, so the right pick depends on what matters most when you fill a pen.
Quick verdict
Pick Private Reserve Infinity if extended cap-off time is important during your writing routine. Choose Rich Bright Colours if a lower listed price and a multicoloured ink direction are the stronger priorities. The products share a bottled format, but their clearest differences are the writing feature, color presentation, and price.

Where each product wins
Private Reserve Infinity
Private Reserve Infinity stands out for its explicitly described resistance to fading and feathering. That makes it the more relevant choice for shoppers who are focused on those stated characteristics rather than simply looking for a colorful ink selection. Its extended cap-off time is another concrete reason to consider it when a pen may be left uncapped during a writing session.
Rich Bright Colours
Rich Bright Colours has the clearer colorful identity. The title emphasizes rich bright colours, and the ink color is identified as Multicoloured. That gives it a direct fit for a shopper who wants color variety represented in the product choice, while its lower listed price keeps the initial purchase amount straightforward to compare.
Product notes
Private Reserve Infinity Fountain Pen Ink Bottle
Private Reserve Infinity is the better match for writing sessions where a pen may remain uncapped: extended cap-off time is its clearest practical reason to choose it. The listed color is Black, making the selection direct for black-ink writing. The limitation is easy to quantify: the bottle is listed at USD 16.95, which puts it USD 12.47 above Rich Bright Colours. That price difference matters if the goal is simply to choose a lower-priced bottled ink. The black selection also makes it less aligned with a shopper whose main brief is a multicoloured ink presentation.
Rich Bright Colours Fountain Pen Ink
Rich Bright Colours suits shoppers who want a color direction labeled Multicoloured and a lower listed price. The title's "Rich Bright Colours" wording reinforces that colorful intent, while the 30ml bottle matches the volume of Private Reserve Infinity. Its limitation is the listed material: plastic. That detail may matter to a shopper comparing the physical presentation rather than ink color alone. The color is also presented broadly rather than as the explicitly listed Black shade attached to Private Reserve Infinity, so this is the less direct fit for a single-color black-writing brief.
Final choice by use case
- For black ink: Choose Private Reserve Infinity, whose listed color is Black.
- For a lower-priced 30ml bottle: Choose Rich Bright Colours at USD 4.48.
- For the shared bottled volume: Either product matches the listed 30ml format, so decide using the color direction, cap-off-time feature, and price priorities above.
The simplest decision is therefore feature-led: Private Reserve Infinity is the focused black-ink choice with extended cap-off time, while Rich Bright Colours is the lower-priced multicoloured alternative.
