For converters, cleaning & pen cases, the main decision is whether you need black ink and a refill route or a dedicated fountain pen cleaning tool. These two choices serve different jobs, so the useful shortcut is to match the purchase to your immediate pen task rather than comparing them as interchangeable supplies.

Product notes
Variety Black Fountain Pen Cartridges + Gift Converter
For routine ink replenishment, Variety Black Fountain Pen Cartridges + Gift Converter is the more direct match: it combines black cartridges in two bore sizes, 2.6mm and 3.4mm, with a gift fountain pen converter. The 20-cartridge assortment gives a shopper a choice between the two formats named for the pack, while the black ink keeps the purchase focused. At USD 8.99, it is the lower-priced route in this comparison. The important limitation is the converter: it may not fit a shopper's pen, so the pack is most relevant when the cartridges are the main draw. Its role is ink and refill setup, not the four-part cleaning-tool format of the competing kit.
Fountain Pen Cleaning Kit
When the job is cleaning a fountain pen, Fountain Pen Cleaning Kit is the more relevant match. Its plastic tool has four named parts-an increased-pressure section, suction hose, damping ring, and connecting head-and its size guidance is 5.6mm. Those details make the intended purchase clear: cleaning equipment rather than an ink refill. At USD 11.20, it is the higher-priced item here. The limitation is that the size guidance is specific, so the kit requires a shopper to match a pen's caliber to 5.6mm before treating it as the right choice. Its purpose differs from the cartridge-and-converter format. Choose it for cleaning, not for stocking black ink.
Final choice by use case
- Need ink and a refill route? Choose Variety Black Fountain Pen Cartridges + Gift Converter for its cartridge-and-converter format and black ink focus.
- Need a cleaning tool? Choose Fountain Pen Cleaning Kit because its product format is built around fountain pen cleaning.
- Still undecided? The $2.21 difference matters less than purpose: the cartridge pack addresses ink, while the cleaning kit addresses pen maintenance. Match the purchase to the task you will perform first.
