Used in two ink pens, one a broad point other regular ink pen and both didn't clog after about 4 weeks use. Used broad point to practice calligraphy and improve writing technique. Is this ink permanent on good quality paper? Ink description should say yay or nay!

What is your opinion of the quality of this item? This ink is beautiful! It is a wonderful blue-black and flows beautifully. This is my first try of Fahrney's ink and now I want to try the others. Absolutely! Perfect match, ideal size bottle and I would buy it again! Fountain pen ink.

What is your opinion of the quality of this item? Every bit as good as more expensive inks I've purchased at Fahrney's. Performs just as well as more expensive inks I've used--it's a great value! Blue-black ink as always been my preferred color. Midnight Blues lives up to my preference. Also purchased Black Cherry based on another customer's positive on-line review and I like it a lot. Both inks flow smoothly and are true to color.

What is your opinion of the quality of this item? Was intrigued by the name of this ink for my Sheafer Imperial and decided to give it a try. Glad I did! Immersive color, smooth and delicious. Great price. Love it. Meets my needs perfectly.

What is your opinion of the quality of this item? I own an entire collection of pens and they all earn their keep.

What is your opinion of the quality of this item? I like inks that show some originality. My grandfather, may he rest in peace, used to use a strong purple ink, and that was his signature. When it was my turn, I chose a blue-black ink and an olive green one. I like them both--the olive comes from Fahrney's. I decided to try another blue, Fahrney's Sonic Blue, and find that it compares favorably to WAterman's blue-black, which I've used for maybe 15-20 years. Sure. I like it and may end up mixing it with the Waterman ink.

What is your opinion of the quality of this item? I have used nothing but Mont Blanc in my MB pen until now. I just balked at the price tag. This Fahrney's ink is just as good at just half the price for twice the amount. I'm loving it! Definitely true to its value. As good as the high priced alternatives. Functions as well as any high priced, quality ink.
