This glass inkwell from TWSBI has a black anodized aluminum top with blue accents. It has an ink capacity of approximately 50ml.

You can use the specific upper cap design to cleanly and directly fill your TWSBI Diamond 580, Classic, Mini, or Precision fountain pen, or simply unscrew the upper cap to fill any fountain pen from the inkwell itself.

The top of this Diamond 50 Inkwell is also interchangeable with the top of the TWSBI 70ml ink bottles.
