Ink bottle Diplomat Diplo Octopus glass 30 ml orange

Diplomat Diplo Octopus glass 30 ml orange is a fountain pen ink supplied in a compact glass bottle designed for reliable refills. The formula is intended for fountain pens and provides a vivid orange color with consistent flow characteristics suitable for writing, sketching, and creative applications. The 30 ml glass container allows controlled filling of converters and disposable cartridges while minimizing exposure to air.

Advantages

The ink offers steady feed and predictable drying behavior, reducing feathering and maintaining legible strokes on standard fountain-pen-friendly papers. Its bright orange pigment yields good color saturation for everyday notes and decorative accents. The glass bottle design facilitates precise pouring and stable storage, while the formulation is compatible with most non-permanent fountain pens when used as recommended.

How to use

Ensure your fountain pen is clean before refilling to avoid contamination. For converters, submerge the nib and feed into the ink and operate the converter to draw ink into the reservoir. For cartridge refilling, follow the cartridge or adapter instructions and fill slowly to avoid spills. Wipe the nib and surrounding section with a lint-free cloth after filling. Allow a short drying interval before closing the cap or putting the pen away to prevent transfer to other surfaces.

Usage recommendations

Use on papers rated for fountain pen inks to minimize bleed-through and feathering. If the pen will be unused for extended periods, flush with clean water before storage. Store the glass bottle upright in a cool, dry place away from direct sunlight and keep the cap tightly closed to preserve color consistency and prevent evaporation.
