Choosing fountain pen inks can be confusing when one item is bottled ink and the other is a filling accessory. The key question is whether you need ink to write with or a way to draw ink into a compatible Cross pen. That distinction makes this comparison straightforward: these are different purchases, not two versions of the same writing supply.
Quick verdict
The Rich Bright Colours Fountain Pen Ink 30ml Bottle DIY Accessories is the direct choice for bottled fountain pen ink, with a listed 30ml volume and a price of USD 4.48. The Cross Fountain Pen Ink Bottle Converter, Fits All Models is a slide-operated converter for Cross fountain pens, priced at USD 13.95. Choose Cross when the accessory is the missing part of your pen setup; choose Rich Bright Colours when the ink itself is what you need.
Price and role comparison
| Product | Listed price | Primary role |
|---|---|---|
| Cross Fountain Pen Ink Bottle Converter | USD 13.95 | Slide-operated converter for Cross fountain pens |
| Rich Bright Colours Fountain Pen Ink | USD 4.48 | 30ml bottled fountain pen ink |
Where each product wins
- Cross wins for a compatible Cross pen setup. Its description names lines including Century, Townsend, Century II, ATX, Bailey, Calais, and Sauvage, making the pen family the central buying consideration.
- Rich Bright Colours wins for a direct ink purchase. The 30ml bottle format and USD 4.48 price suit shoppers looking for fountain pen ink rather than a pen accessory.
Product notes
Cross Fountain Pen Ink Bottle Converter
Cross Fountain Pen Ink Bottle Converter is the more suitable choice when the purchase goal is a refill accessory rather than another ink color. Its slide converter operates by moving the piston up and down, and the description names Cross lines including Century, Townsend, Century II, ATX, Bailey, Calais, and Sauvage. That pen-line detail is the key reason to choose it. The limitation is equally concrete: Spire and Classic Century pens with a screw-on cap are specifically excluded. The USD 13.95 price also places it above the Rich Bright Colours bottle, so selecting Cross makes sense when a converter is what the pen setup requires, not when you simply need ink.
Rich Bright Colours Fountain Pen Ink
Rich Bright Colours Fountain Pen Ink is aimed at the shopper who wants bottled fountain pen ink in a clearly stated 30ml format. The title identifies "Rich Bright Colours," while the color information describes the ink as "Multicoloured" and also uses the label "B." Those details give the purchase a distinct color-oriented profile and make it the direct pick for adding bottled ink to a fountain-pen supply. The limitation is that its title presents it as ink and DIY accessories, so it is not the direct match for someone seeking a Cross filling converter. Its plastic material is also part of the product description, which helps distinguish it from an accessory-only purchase.
Final choice by use case
Choose Cross Fountain Pen Ink Bottle Converter, Fits All Models if you need the slide-operated accessory for a compatible Cross fountain pen. Choose Rich Bright Colours Fountain Pen Ink 30ml Bottle DIY Accessories if you need bottled fountain pen ink. The practical decision is function-first: one handles the filling task, while the other supplies the ink.
