on saleNoodler's Whiteness of the Whale - 1oz Bottled Ink

to spend on this ink, grab a UV light and check out any inks you've mixed it with. You've turned your ink into a forgery proof ink - and if you're using *this* to lighten up your inks, you can definitely find less expensive ways to do that. But, if you create UV art or want to make sure you can prove that a signature is *your* signature, this is a steal. A lot of Noodler's inks are tremendously awesome under blacklight on the right papers.

I write letters to my kids that they can only read. We have a blast.

Only good with UV light on black paper. And there are other inks better for UV light. Other Noodler's inks are great but this one doesn't pass the test.

I used this with my CMYK both to add some document permanence and to lighten up my ink mixes to bring out colors (so many are so heavily pigmented that they're almost black, and water can make them a bit feather-ey)It does both jobs with absolute perfection. This takes my dark blue-green and makes it electric turquoise. It also takes my mixtures and makes them a bit less prone to feather, too.My only complaint whatsoever is that it's 3x as expensive as normal noodlers inks, when it's almost a base color. I know nathan is absolutely not trying to rip anyone off, but I do wonder what makes this stuff so bloody expensive!Four stars because it's so expensive, but it's still absolutely essential to a good noodlers CMYK.

Simply no fluorescence, no dark light shining. I have a money checker dark light source at home also Noodler's sent me a finger attached UV light duheckey as a gift, both gave no shining contrary to as shown in Nathan Tardif's video. I thought my batch might be bad, I've sent a full sample vial to Goulet's back so they can check my bottle is bad or not. They reported back nothing wrong with my ink. So my suspicion is gone, this ink doesn't shine on black light at all, just a dull white. You can only use for kighten your ink colors that all. Great disappointment
