10 Best Fountain Pen Inks 2025 in the United States

The Asvine Hongdian Fountain Pen Bottled Ink in blue is a solid choice for fountain pen enthusiasts looking for quality and performance. One of its key strengths is the smooth flow of ink, which ensures a pleasant writing experience without clogging issues thanks to its non-carbon formulation. Users can expect quick-drying properties, making it suitable for left-handed writers and those who prefer a faster turnaround when writing without smudging. The ink's vivid color adds a stylish touch to any penmanship, enhancing writing aesthetics.

The 60ml glass bottle is thoughtfully designed with a wide base and tight-sealing lid, which is great for storage and prevents spills, but be mindful that glass can be fragile. The ink's pH neutrality and non-toxic nature are additional benefits, making it safe for regular use.

Some users may find that while the ink flows well, it might not be as water-resistant as other premium inks on the market. This means that in case of spills or exposure to water, the writing may smudge or wash away. Additionally, while the ink is marketed for all types of fountain pens, some users with specific pen models may not achieve the same level of performance, so it's always a good idea to test it first.

The PILOT Iroshizuku Bottled Fountain Pen Ink in Shin-Ryoku, or Forest Green, is a great option for fountain pen users who appreciate high-quality ink. One of its standout features is the rich, deep green color that captures the essence of Japanese nature, making it visually appealing for writing or journaling. Users often find that the flow of the ink is smooth, allowing for a pleasant writing experience without skips or blotches, which is a crucial factor for those who write frequently. Additionally, this ink generally dries at a reasonable speed, reducing smudging, particularly for left-handed writers.

In terms of water resistance, the Shin-Ryoku ink is somewhat limited. If you expect your work to be exposed to moisture, this might not be the best choice, as it can bleed when wet. However, the ink does provide beautiful shading effects, adding character and depth to your writing. For those who enjoy the aesthetic of varying tones in their text, this feature can be quite appealing.

The ink is sold in a 50ml bottle, which is a good size for regular use without being overwhelming. Plus, the trusted quality of the Pilot brand reassures users that they’re getting a reliable product. On the downside, some users may find this ink slightly on the pricier side compared to other brands. Additionally, while the aesthetic qualities are superb, those who prefer practical, everyday writing might lean towards more water-resistant options instead. The PILOT Iroshizuku Shin-Ryoku ink is a fantastic choice for those who value color and shading in their writing, but it might not suit everyone's practical needs.

The Montblanc Ink Bottle in Royal Blue is a premium choice for fountain pen enthusiasts, calligraphers, and anyone looking to elevate their writing experience. One of its standout features is the elegant and deep blue color that adds a touch of sophistication to any piece of writing, making it especially suitable for formal documents and creative projects alike. Users appreciate its smooth flow, which prevents clogging and ensures a consistent application, a key requirement for fountain pen inks. Additionally, the quick-drying property of the ink helps to minimize smudging, which is a significant advantage for left-handed writers or anyone who tends to rush their writing.

However, this ink isn't without its drawbacks. While it is highly regarded for its water resistance, it may not be completely waterproof, which could be a concern for those needing absolute permanence. The drying time is generally swift, but some users might still find it a bit longer compared to other inks on the market. Furthermore, being a premium product, it comes at a higher price point than some budget alternatives, which might not appeal to everyone.

The Montblanc ink bottle is also beautifully designed, making it a stylish addition to any desk. However, its vintage pot design, while attractive, may not be as practical as modern ink bottles for some users who prefer easy refilling mechanisms.
