A small but mighty upgrade for your Kaweco fountain pen. The Kaweco Sport Mini Piston Converter allows you to use bottled ink with any Kaweco Sport series fountain pen, including the AL Sport, AC Sport, Ice, Classic and Skyline models. Simply screw it in where the cartridge would go and fill via the twist-action piston—neat, efficient, and far more satisfying than disposable cartridges.

Please note: this converter is not compatible with the Kaweco Lilliput.

Features:

• Compatible with Kaweco Sport Series: Fits AL Sport, AC Sport, Ice, Classic, and Skyline

• Piston Mechanism: Twist-action filling from bottled ink

• Reusable and Convenient: A sustainable alternative to cartridges

• Not Suitable for Lilliput: Designed specifically for the Sport series only

• Compact Size: Perfectly sized to fit within the Kaweco Sport barrel
