When shopping for converters, cleaning & pen cases, the key choice here is not simply which tool costs less. Do you need to remove ink residue from a nib and feed, or do you need a more controlled way to move ink into a converter cartridge? These two fountain pen tools serve different jobs, so the right pick depends on the task your pen routine requires.
Quick verdict
Choose the Fountain Pen Cleaning Kit for Standard 5.6mm Nibs when cleaning is the priority, especially if the standard 5.6mm specification matches your pen. Its stated purpose is removing ink residue and debris from the nib and feed, and its clear plastic design is intended to make the process easier to observe.
Choose the 5pcs Hongdian Fountain Pen Filler Ink Pen Syringe Absorbor Device Tool when refill handling is the main concern. Its description focuses on ink converter cartridges, small amounts of ink, and avoiding direct nib contact with the ink. It is priced at $12.99 versus $20.99 for the cleaning kit, an $8.00 spread.

Product notes
Fountain Pen Cleaning Kit for Standard 5.6mm Nibs

The strongest reason to choose this kit is its direct cleaning focus. It is described as a plastic tool for removing ink residue and debris from a fountain pen's nib and feed, while the clear design allows the cleaning process to be observed. That makes it the more natural match for routine maintenance rather than ink transfer. Its concrete limitation is the stated fit for standard 5.6mm nibs, so that specification should align with the pen you intend to clean. The title also frames it as a cleaning kit, not a converter-filling accessory. For a shopper dealing primarily with buildup or residue, the clearly defined cleaning purpose is more relevant than the additional trim and ink-color attributes.
Hongdian Fountain Pen Filler Ink Syringe Tool

The Hongdian tool is aimed at a different frustration: getting ink into a converter when only a small amount remains in a bottle or when dipping the nib would be awkward. Its description specifically discusses ink converter cartridges and names Moonman and Hongdian pens, giving it a clear refill-oriented role. The metal material is another concrete attribute, but it does not by itself establish a performance advantage. The limitation is scope: its stated use centers on filling and absorbing ink, not cleaning residue from a nib and feed. If the main job is pen maintenance after changing colors, this tool does not offer the same explicitly described cleaning function as the kit above.
Final choice by use case
- For cleaning a nib and feed: Pick the Fountain Pen Cleaning Kit, with its plastic cleaning tool, clear design, and standard 5.6mm nib specification.
- For filling an ink converter: Pick the Hongdian Fountain Pen Filler Ink Syringe Tool, whose description is centered on converter cartridges and controlled ink absorption.
- For avoiding direct nib contact during filling: The Hongdian tool is the more relevant match because that use is specifically described.
- For a defined cleaning accessory: The Fountain Pen Cleaning Kit is the better fit because cleaning is built into its title and stated purpose.
The final decision is straightforward: buy the cleaning kit for residue and feed maintenance, or choose the Hongdian tool when the immediate need is moving ink into a converter with less mess around the nib.
