Monteverde Mulberry Noir Ink Bottle, Purple - 30ml

Monteverde Mulberry Noir Ink Bottle, Purple - 30ml

This bottle—part of the “Noir” collection from Monteverde USA—offers a deep, rich purple ink that blends a vibrant mulberry hue with black, resulting in a shade that at first glance appears nearly black, but upon closer inspection reveals its purple character. 

It comes in a 30?ml glass bottle, making it a practical size for regular use rather than just a miniature sample. The package emphasises compatibility with fountain pens and the enhanced performance via Monteverde’s proprietary "ITF" (Ink Treatment Formula).

Specifically:

• Colour: “Mulberry?Noir” = deep purple + black.

• Collection: The “Noir Ink Collection” — described as “vibrant ink colours blended with black ink, creating a mixture of mysterious, bold and expressive fountain pen inks.”

• Formulation: ITF technology — designed for improved ink flow, extended cap?off time, lubrication and protection against feed corrosion/clogging.

Appearance & Behaviour

Colour & Visual Character
When used in writing or swabbing, the Mulberry?Noir comes across as a very dark purple, almost black in some lighting or when used in fine nib/low ink load. Under broader nibs or heavier ink flow, the purple hue shows more clearly, revealing its mulberry (reddish?purple) tone combined with black depth. Reviews emphasise that it is “a deep purple blended with black, a rare colour in nature, royal and true.” 

Because of the black blending, the shade is more subdued and sophisticated compared to bright purples. It may show subtle shading (variation in tone depending on ink load and nib flow) though I did not locate many user?review details about sheen or dramatic colour shifts for this exact variant.

Writing Performance & Flow
The ITF formulation suggests that this ink is engineered for smooth flow and good pen compatibility. In the product listing: “The world’s leading European ink treatment formula (ITF)” and “Deep purple blended with black … Express your brightest and deepest thoughts with this line of powerful fountain pen inks.” 

Because of the dark nature of the ink (due to black blending), it may behave somewhat more forgivingly (less prone to show?through or brightness) than brighter purples—but as always, pen nib size, paper quality, and ink flow will affect how the colour appears and performs.

• For writing where you want a purple tone but also a more formal or subdued aesthetic (thanks to the black?leaning darkness).

• For journaling, expressive writing, personal correspondence where colour counts but readability remains high.

• For collector use: the Noir collection has strong appeal for those interested in colour variants or special editions.

• Works well with a medium or broader nib and fountain?pen friendly paper to maximise the visible tone of the purple.

• Sophisticated purple: The blend of purple + black gives a refined tone—less flashy than neon or pastel purples, more elegant and understated.

• Collector?friendly: Being part of the Noir collection gives this ink extra appeal to enthusiasts of fountain?pen ink.

• Practical size: 30?ml bottle is functional and usable rather than overly large.

• Good performance backing: ITF technology suggests solid pen compatibility and flow rather than just a novelty colour

• Because it's dark (black?infused), the “purple” may appear near?black in fine nibs or light strokes—meaning you might miss the purple character if your pen is dry or the paper minimal.

• If you expect strong sheen or dramatic colour shifts (as some bright purples offer), this ink may be more subtle. I did not locate reviews highlighting strong sheen for this particular variant.

• As with many fountain pen inks, the behaviour will depend heavily on the paper and pen—on cheaper absorbent paper you might see less crispness, slower drying, or less visible colour variation.

• While Monteverde inks are generally well?rated, there have been user reports of quality/contamination issues (e.g., mold in some bottles) across older batches of Monteverde inks. Example: > “I discovered mold in my bottle of Copper Noir …” While not specific to this bottle, it’s wise to inspect upon receip

• Use with a pen of moderate to good ink flow (preferably medium/broad nib) to bring out the purple tone distinctly.

• Pair with good paper (smooth, moderate absorption) so you can appreciate the colour depth and avoid feathering or bleed.

• When filling, if the writing appears too dark/black and you want more purple, consider a wetter nib or heavier ink load (e.g., slower writing, pause on strokes) to let the colour reveal itself.

• Store the bottle upright, cap tightly, keep away from extreme heat/sunlight—especially important for dark canned inks where sediment/mold issues may be more visible.

• If you plan to use this ink in a demonstrator or clear?body pen, test a sample first to ensure you like how the purple shows in your specific setup (pen + paper + lighting).

• For readability/archival tasks, ensure the writing contrast is good (dark purple may still show as dark, but readability vs black can vary depending on light/paper).
