When I received few weeks ago a package from BureauDirect, UK containing 11 sets of cartridges of different Monteverde’s ink colours for testing, two of them brought my attention. Apart of 9 let’s say standard ink and colours parcel contained two bizarrely looking types lurking. My first reaction was What on Earth is that?… and for God’s sake why ? These two sets of cartridges contains very bright and cloudy liquids which someone by mistake dared to call ‘an ink’, I thought. These two inks Fluorescent Yellow and Fluorescent Orange (please see my recent reviews) look exactly like fluorescent fluid commonly used in the office text highlighters. Immediately, I was thinking, OK why we fountain pen users need an ink like that. I have set highlighters on my desk and my drawer, I am fine with them. Then, I did reviews of 9 ‘standard’ Monteverde inks and start to face there two lads, and here they are. There are good and bad news about them. The bad is that these ‘inks’ are not for daily writing. They are just too bright. Additionally, I would not use them with any expensive pen. Both have intriguing viscosity which may (or may not) cause troubles. The good thing is that these inks are super cool to play with – both glow under UV light, reminding toxic and radioactive nuclear waste dump. Additionally, the flow ind lubrication is awesome. I would not mind if most of my inks perform on the paper like Fluorescent Yellow – just a pure pleasure. The general application of this ink would be purely editorial with text corrections and markings. For quick flashy notes as reminder these two inks are fine. Highlighting text is an option too, but rather if you have pen equipped with wider italic nib.
