Noodler's Ink Refills Firefly Bottled Ink - ND-19170

I was using the limited edition lamy charged green, which worked as a highlighter ink but left a pallid, pale yellow highlight.This stuff is exactly what I wanted. it has that bright neon green lego color, and works wonderfully. I use it in a pilot parallel 3.8 that I ground on sandpaper to resemble a highlighter tip. I then put the parallel nib in a Moonman M2 and I'm never buying another highlighter in my life. This is all I will ever need.

Love the color and transparency! Works great for highlighting my books! I would be happy to purchase this brand again! I love that it is made in the USA. Bottle of ink was full — almost overflowing. Great it you are tired of highlighters that quickly run out of ink.

Awesome color highlighter! Looks great under UV black light. Bleeds though a lot though. But still really cool.

Snagged last "glass bottle". Amazon has multiple stores for the product and it constantly changes. So you can't get a service after a while because you can't trace the company that sold you this one. But as far as ink goes, it's bright and awesome. Thanks!

One of my favorite inks. So bright and cool

As expected

I use this ink in my Pelikan highlighter fountain pen. I had been using the Pelikan ink, but this is much better. Flows much more freely. The downside is that if you are highlighting lousy copier paper it can show through. However, the ink color is so light that really isn't an annoyance. Also, unlike some other highlighter inks, you can use this ink in any fountain pen.
