Where each product wins
Variety Black wins for ink flexibility
The Variety Black set is the practical pick when your immediate goal is refilling a fountain pen. Its 20 black cartridges are split between 10 with a 2.6mm bore and 10 with a 3.4mm bore, and the package includes a gift fountain pen converter. That combination gives the set a clear role in an ink-focused routine, especially when you are unsure which of the two listed cartridge sizes suits your pen. The description also identifies an important boundary: pens from companies such as Parker and Pilot may use proprietary cartridges.
Montblanc Meisterstück wins for single-pen carry
The Montblanc Meisterstück pouch is the more relevant choice when storage matters more than ink replenishment. Its title identifies a black leather pen pouch and single-pen holder, while the attributes specify leather as the material. This is a focused accessory for carrying one writing instrument rather than a refill assortment. The title's "No Box" wording also makes the presentation format clear, so it is best suited to shoppers choosing the pouch itself for single-pen organization.
Product notes
Variety Black 20 Fountain Pen Ink Cartridges + Gift Converter

This set makes sense for a writer who wants black ink cartridges while keeping two commonly listed bore sizes in one package. The combination of 10 cartridges at 2.6mm, 10 at 3.4mm, and an included converter gives it a concrete advantage for shoppers comparing those specific refill formats. At USD 8.99, it also keeps the purchase centered on ink supplies rather than storage. The limitation is fit uncertainty: the description says the gift converter may not fit every pen, and it identifies Parker- and Pilot-style proprietary cartridge systems as exceptions. If your priority is protecting or carrying a single fountain pen, the cartridge count and converter are not a substitute for a dedicated pouch.
Montblanc Meisterstück Black Leather Pen Pouch Case Holder

The Montblanc Meisterstück is the straightforward choice when one pen needs a dedicated holder. The black leather construction and single-pen format give it a clearly defined storage role, and the description positions it for work, travel, or daily professional use. It is therefore easier to justify when your routine already has an ink solution and the missing piece is a sleeve-like place for one writing instrument. Its limitation is scope: this is a single-pen pouch, not a cartridge or converter set. The title also specifies "No Box," so shoppers choosing it are selecting the leather holder rather than a boxed presentation.
Final choice by use case
- Choose Variety Black for black fountain pen refills, two listed bore sizes, and an included gift converter at USD 8.99.
- Choose Montblanc Meisterstück for a black leather, single-pen holder at USD 27.99.
- If fit is the deciding issue, the Variety Black description specifically flags proprietary Parker and Pilot cartridge systems and cautions that the gift converter may not fit every pen.
- If storage is the deciding issue, the Montblanc Meisterstück's single-pen pouch format is the direct match.
For an ink-supply purchase, Variety Black is the clearer fit. For carrying one fountain pen in leather, the Montblanc Meisterstück is the more relevant choice.
