Quick verdict
In converters, cleaning & pen cases, the key decision is whether you need to maintain a pen or manage its ink supply. The Fountain Pen Cleaning Kit is the more direct match for cleaning work, while the Set of 2 Monteverde Mini Fountain Pen Converter+ refill Syringe/Converter-2.6mm is aimed at filling and converter use. A $0.75 spread separates the two, so the task matters more than the small price difference.

Where each product wins
Fountain Pen Cleaning Kit: cleaning-first choice
The Fountain Pen Cleaning Kit wins when the immediate job is cleaning a fountain pen. Its description lays out a four-part assembly with an increased-pressure section, suction hose, damping ring, and connecting head, giving it a clearly defined maintenance role. The listed 5.6mm pen fit is the detail to focus on when deciding whether it matches your pen.
Monteverde Mini Fountain Pen Converters: refill-first choice

The Set of 2 Monteverde Mini Fountain Pen Converter+ refill Syringe/Converter-2.6mm wins for converter and refill work. Its included piston syringe converter can refill the mini converters or function as a standard converter, making the set more directly suited to ink-handling tasks than to cleaning.
Product notes
Fountain Pen Cleaning Kit

The Gilprop Fountain Pen Cleaning Kit is a sensible pick when pen maintenance is the goal rather than converter capacity. The four-part design-pressure section, suction hose, damping ring, and connecting head-gives the kit a specific cleaning setup, and the description calls out simple operation. Its main limitation is the listed fit: it is described as suitable for a 5.6mm pen and specifically for Japanese caliber 5.6mm, so that measurement is central to the choice. The package contains one kit, and its plastic construction is plainly specified. Choose it for the cleaning-focused function named in the title; pass on it for a converter-centered routine where refill equipment is the priority.
Monteverde Mini Fountain Pen Converters
The Set of 2 Monteverde Mini Fountain Pen Converter+ refill Syringe/Converter-2.6mm is the better match for someone who wants converter components and a refill method together. It includes two mini converters with 2.6mm bores and a piston syringe converter that can refill them or serve as a standard converter. That gives the set a clear ink-handling purpose. The limitation is equally concrete: its description is centered on converters and refilling, not on a multi-part pen-cleaning assembly. The 2.6mm bore is described as standard for most fountain pens, but it remains the key listed dimension to compare with your intended pen. Choose Monteverde when refill flexibility is the deciding feature.
Final choice by use case
- For cleaning a fountain pen: Choose the Fountain Pen Cleaning Kit, because its title and four-part cleaning assembly directly match that task.
- For filling or using converters: Choose the Set of 2 Monteverde Mini Fountain Pen Converter+ refill Syringe/Converter-2.6mm, because it combines mini converters with a piston syringe converter.
- For the lower listed price: Choose the Fountain Pen Cleaning Kit; the price spread is $0.75.
- For a gift aimed at pen maintenance: The Fountain Pen Cleaning Kit is the more relevant match because its description explicitly presents it as a simple cleaning tool and gift option.
The short version: buy the Fountain Pen Cleaning Kit for cleaning, and choose Monteverde when converter refilling is the reason for the purchase.
