Glass ink bottle Diplomat Diplo Octopus, 30 ml capacity, bordeaux color. This compact glass bottle is designed for fountain pen and calligraphy ink use, offering a stable container that eases filling converters, pistons and eyedroppers. The deep bordeaux shade provides a rich red tone for writing and drawing, while the glass construction preserves ink quality and allows visual monitoring of remaining volume.

Advantages

Transparent glass lets users check ink level at a glance, and the secure screw cap helps limit evaporation and contamination.

How to use

Place the bottle on a stable, flat surface before opening the cap.

After refilling, wipe any excess ink from the pen and bottle rim, then close the cap firmly to minimise evaporation and contamination.

Usage recommendations

Store the bottle upright in a cool, dry place away from direct sunlight. Shake gently only if the ink manufacturer advises suspension of pigments; otherwise avoid unnecessary agitation. Keep cap tightened when not in use and handle on a protected surface to prevent stains; use suitable cleaning materials to remove accidental spills.
