TWSBI Diamond 50 Ink Bottle - 50 ml - Polished Aluminum

TWSBI Diamond 50 Ink Bottle — Polished Aluminum (50 ml)

A faceted glass inkwell with a polished anodized aluminum cap. The polished aluminum version is the upgraded finish on the standard Diamond 50 bottle, which otherwise ships with a black plastic top. Works with any bottled fountain pen ink and any pen, with extra functionality for TWSBI's piston-filler line.

What makes it special

• Two-part cap: the lower section unscrews for normal bottle filling; the upper section threads directly onto TWSBI Diamond, Classic, and Mini sections so you can fill the pen without dipping the nib
• Internal removable reservoir — flip the bottle (cap on) to load a metered amount of ink, useful when the bottle runs low
• Polished anodized aluminum cap upgrade over the standard black plastic version
  
• Adapter also fits standard international converters
