40ml Fountain Pen Ink in a Glass Bottle: 12 Colour Choices for Smooth Writing

This fountain pen ink provides a straightforward, practical refill option for daily writing tasks. Supplied in a 40ml glass bottle, the ink is formulated to be water-resistant and non-volatile, helping to keep pen nibs moist and ready for use while offering a choice of twelve distinct colours. Its design caters to common needs in educational and professional settings, where reliable, odour-free ink is a priority. The range includes both traditional and less common shades, from standard blacks and blues to greens, browns, and brighter options like orange, pink, and yellow.
Features and Construction

The product centres on a functional ink formulation presented in a simple, reusable container. Its key characteristics are derived from its capacity, material, and colour variety.
Material and Build
The ink is contained within a glass bottle. Glass is a common material for ink storage as it is inert and helps preserve the ink's properties. The ink itself is described as water-resistant and non-volatile, which are practical features aimed at maintaining legibility and preventing the pen nib from drying out between uses. The formulation is also noted for having no odd smell, which is a practical benefit for users in shared spaces like offices or classrooms.
Size and Practical Fit
The ink bottle has a 40ml capacity. This volume represents a standard, mid-sized option for fountain pen ink, offering a substantial amount for regular use without being overly large. The product is offered in twelve different colour variations: Black, Blue, Blue black, Brown, Green, Light blue, Light green, Navy, Orange, Pink, Red, and Yellow. This provides a broad selection to suit different preferences and purposes, from formal document writing to more creative or personal notation.
Uses and Placement

This ink is designed for specific writing instruments and environments. Its properties make it suited for general, everyday writing applications.
Event or Professional Use
The water-resistant nature of the ink suggests it can be used for documents where longevity and resistance to smudging or accidental spills are valued. Its range of colours, including formal shades like black, navy, and blue-black, supports professional or academic writing, note-taking, and record-keeping. The absence of odour makes it discreet and suitable for use in shared workspaces or libraries.
Everyday Home Use
For personal journaling, correspondence, sketching, or hobby use, the wider colour palette offers flexibility. Shades like brown, green, orange, pink, red, and yellow allow for more personalised or creative projects. The 40ml bottle size is convenient for home use, providing enough ink for regular writing over an extended period without requiring frequent replacement.
Benefits and Buying Value

The value of this product lies in its combination of a practical ink formulation, a reusable glass bottle, and a wide colour selection.
Reuse and Low Maintenance
The glass bottle can be kept and reused once the ink is finished, potentially for other small storage needs. The ink's non-volatile characteristic is a form of low maintenance, as it helps prevent the pen nib from clogging or drying out if the pen is not used for a short period. Proper care, such as screwing the cap on tightly after use, is the primary maintenance required to preserve the ink.
Why Choose This Product
This product offers a specific set of features: a 40ml volume, a water-resistant and odour-free ink formulation, and a choice of twelve colours. It is presented as a good choice for school or office use, aligning its benefits with environments where reliable, clean writing is important. The explicit instruction not to mix it with other ink types underscores that it is formulated specifically for fountain pens. Buyers choosing this ink are selecting for its stated practical properties and colour range rather than unsubstantiated premium claims.
