The Ultimate Guide to Sheaffer Pen & Pencil Refills: Understanding Basic Refill Types
Sheaffer Ballpoint Refills
Sheaffer ballpoint pens are popular for their smooth writing and reliability, but selecting the correct refill size and style is vital. Sheaffer mostly uses proprietary refill sizes alongside some standard options. The common refill sizes include:
- C1 (C Style): A popular Sheaffer ballpoint refill compatible with many classic models. Known for reliable ink flow and a medium writing point.
- G2: The industry standard refill size used by many brands, including some Sheaffer pens like the Taranis and Sagaris.
- D1: A smaller, slimmer refill often found in multifunction pens or compact Sheaffer models.
- K Style: A proprietary refill made specifically for select Sheaffer ballpoints requiring a unique fit and ink formulation.
Sheaffer ballpoint refills are generally available in black or blue ink and come in fine and medium point options to suit personal writing styles.
Sheaffer Fountain Pen Refills and Cartridges
For fountain pen enthusiasts, Sheaffer fountain pens use either standard international ink cartridges or their proprietary cartridges depending on the model. Additionally, some Sheaffer fountain pens can accommodate a piston converter, allowing ink refilling from bottled sources—ideal for frequent users who prefer a variable ink choice.
Key tip: Check your fountain pen model details or manufacturer's guide to determine if it uses standard international cartridges, a proprietary cartridge, or the piston converter system to avoid purchasing incompatible refills.

How to Identify the Right Sheaffer Refill Size for Your Pen
Measuring the Refill Length
One of the most practical ways to identify the correct refill size is by measuring the refill itself. The length of the refill cartridge typically corresponds with Sheaffer’s sizing conventions:
- C1 Refill: Approximately 95-96mm in length
- G2 Refill: About 98-102mm long, standard for many ballpoint pens
- D1 Refill: Much shorter, usually around 67-70mm for slim designs
- K Style: Varies, often proprietary length depending on pen model
Using a ruler or caliper to measure your old refill’s length can quickly narrow down the refill options.
Examining Refill End and Tip Design
The shape of the refill’s ends and the feed or tip style offers clues about its compatibility:
- C1 and G2 Refill: Typically have cylindrical bodies with a metal tip and rounded or flat refill ends.
- D1 Refill: Usually thinner in diameter and commonly has a plastic section at the base and metal tip.
- K Style: May have unique end seals or shapes to fit only Sheaffer proprietary pen channels.
Visual comparison with available refill images online or at retailers helps confirm your choice before purchase.

Choosing the correct point size complements your natural writing style and ensures comfort.
Refill Packaging and Authenticity
Ensure that your Sheaffer refills come from reputable sellers or official distributors, avoiding counterfeit products which can lead to poor ink performance or compatibility issues.
