on saleNoodler's Blue Ghost - 4.5oz Bottled Ink with Free Charlie Pen

I purchased this to use with a handout for a roll playing game. I designed the puzzle and then put the clues in using this ink. The players had no clue that the mysterious writing is on the handout, because they haven't hit the ink with UV light yet. I did while testing the ink and it shows up great! I got the idea after watching a YouTube video with an artist who adds a second drawing on top of the first using Noodler's Blue Ghost ink. He said it was the best to use because it showed up really well under UV light, but also didn't react to most inks negatively. This way his original drawing was not affected when he placed the second, hidden drawing on top of it. I would highly recommend this ink if you have an application for it. I haven't tested it for water resistance, and it's difficult to test shading on it.

Love it! Maybe not the most practical day to day ink, but if you have a use case for invisible ink that shows up clearly under a good UV, you won't be disappointed! The included Charlie pen ensures you have a pen that you can dedicate to the ink without traces of another color, and the clear barrel means you'll know when you're out of ink ...which, with invisible ink isn't as much of a given as with most! :). The fact that it's more bulletproof than most of my visible inks is ironic as heck, and an added plus .

Loved the blue ghost noodlers ink. It dries completely transparent so you cannot see at all where you've put down the ink and Glows super bright under a black light. I've been enjoying writing secret messages for my DandD campaign. The free pen that came with the 120mL not so good, leaked and broke in the first use

The real reason I bought this ink was to keep my sketchbooks looking nice. I was gifted some fairly low GSM Masters Touch sketchbooks and unfortunately I can see my drawings through the pages. Heck, I can see dark areas through the next page! Only drawing on one side of the page makes the sketchbooks look cleaner especially with ink but it feels like such a waste of space. Then I saw this and I think my pictures speak for themselves. The Blue Ghost ink looks fantastic in the sketchbooks I bought it for. It doesn't bleed through on most papers. I actually wrote on both sides of the white paper in the picture. It behaves like my standard India inks except it remains wet longer in my opinion which is nice when using dip pens. Cons:This ink bleeds through very thin paper. It feathers with wide tooth paper. The ink did leave a disruption in my more textured toned sketchbook so you could see something is written there but without a black light it would be pretty difficult to read.Overall, I am very satisfied with my purchase. Noodler's Blue Ghost ink does what it is advertised to do. The Charlie pen that comes with it is a nice bonus though it does glob occasionally usually when I first start writing with it. I've only used a small amount of fountain pens but I think this is fine for my invisible ink. Most people probably won't see the mess ups anyway right?

You have to clean your pen really good before using this ink. This is a ' transparent ' ink, any old ink residue on your pen will mix and this won't be invisible anymore. Works great with a broad nib because you don't have to press on the paper for the ink to flow. Leaves no visible traces on the paper. Love it ! I feel like James Bond when I write with this ink!
