Description

The TWSBI VAC 20A Ink Bottle is a compact marvel of sensible design, quietly brilliant at its job. Created by TWSBI specifically for the VAC 700R and VAC Mini fountain pens, this inkwell allows a complete, satisfying fill in a single stroke. No dipping. No topping up. No dramatic blotting of fingers afterwards.

Simply add your ink (not included), replace the cap, screw your compatible TWSBI vacuum pen into the top, extend the plunger, and push. That’s it—the pen fills completely and cleanly, as if it had always intended to. For non-vacuum pens, the clever upper cap can be removed, transforming the VAC 20A into a perfectly serviceable traditional inkwell.

Small enough for desks and travel, and engineered to be genuinely useful, this is one of those accessories you’ll wonder how you managed without—briefly, at least.

Why You’ll Love It

  • One-Stroke Filling: Designed to fully fill VAC pens in a single, elegant motion.

  • Clean and Controlled: Keeps ink where it belongs—inside the pen.

  • Versatile by Design: Works beautifully with VAC pens, and adapts easily for others.

Details

  • Volume: 20ml bottle each
  • Package: 1pc of a 20ml bottle
  • Weight: 2g
  • Bottle Material: Plastic
  • Country of Origin: Taiwan
