But I was disappointed with the ink color intensity

I've been a fan of Uni-ball pens for several  years. I was looking forward to enjoying these pens. I was curious about the novel ink delivery system.
But I was disappointed with the ink  color intensity . Also, the width of the  writing line was more like a 0.5mm line.  I have several Pilot pens. I'm now hesitant about buying any more of these pens/

I purchased these because I needed a dark blue ink.  The ink in these Blue Black cartridges is black - exactly matches all my other black ink cartridges.  I love the pens, but the ink color in this case left me very disappointed.

I received the refills and was very excited until I realized 1/2 were blue and the black.  I ordered black, the refills also appear not to be lasting as long as the ones I bought from local vender, unfortunately I am an unsatisfied customer

This is a good all around multi-function printer, but the color saturation is VERY dull. I've had cheaper printers whose colors were much more vibrant than this.  This is fine, if you don't need crisp color prints.

Ink is weak and messy. The printing was not clean and it had a fading black color to the pages i printed

I was very excited about the beautiful yellow print, but the print looks bolder and on the picture than when it arrived.  Also, I purchased Con-tact paper for part of the project and while the Con-tact paper smoothed and cut well, I ended up with bubbles in the Macbeth collection paper.  Then my 5 yr old ripped up a section of the paper and it would not readhere.  I am returning another roll because the color does not match the appearance on the photos.

Just like the other reviewers, I liked the markers but felt the color of the ink was not true to the packaging

Using heart of darkness and the color is light, The ink is very dark with dip pens. Might be a flow issue

The ink in these pens is translucent and difficult to read.  I bought them because I had been at a recent event where the host used the brand sold at Total Wine (I don't know the brand) and the ink in those pens was thicker and much more opaque.  These do not show up on the glass - especially the two metallic ones - but even the green blue and red are hard to see unless you write on the base and put the glass on a white surface.  In view of the fact my furniture is not white, functionality of these pens is marginal for my use.  Price is comparatively low, but that just means it isn't worth the hassle to return them.  :-[

I was super excited to try this product out. I waited for a gorgeous sunny day to do it, followed the instructions to a "T" and was VERY disappointed with the results. I printed a couple t-shirts, light gray in color, using the black ink that came with the kit. I let one sit in the sun for about 25 minuets and the next just a minute or so longer. Both definitely exposed the ink... somewhat... in the image they were supposed to, but the edges were fuzzy and kinda blended into the gray color of the t-shirt, not sharp lines at all. I honestly did everything I could to make sure the film was as flat as possible so the sunlight couldn't sneak under the film AND I made sure to position the boards so they were receiving 90 degree sunlight. I was left with two shirts with a maroon in color designs that honestly don't look great at all. I'm a pretty crafty guy, and after many more attempts on some used cotton shirts, I was never able to get a finished product I was proud of. Great idea! Just wish the final product was clean and presentable and not embarrassing : (

*****UPDATE****
I take back everything I said originally!! The colored ink is not working well at all. Reds print out orange and the blues are a strange shade of green. I am so disappointed. The black cartridge works well,so I didn't realize how poorly the colored ink is performing until my daughter tried to print out her school project. Very disappointed and do not recommend.

I ordered about 2 weeks ago. I was a little hesitant to order because I had always only purchased brand name ink in the past, but decided to give it a try. So glad I did! The ink works great.  Will order again.

I wanted to go with the cheap ink and I am sorry I did now! The color still has ink in it but the black is completely out, it says since they are refurbished it says the ink is low so I ignored the low ink signal on my PC and it is correct it was way low. The color has about 3 quarters of liquid in it according to my Lexmark ink level (it was 3 quarters when I got it) The black on the other hand was below half almost above the quarter mark but according to ECO INK & TONER INC the Lexmark ink level indicator I have they say on the page before you get it don't worry about that because it is refurbished ink cartage's, well make sure you look at the ink indicator cause I got shammed on this purchase and now I can not return it cause it has been too long (I do not print allot) ECO INK & TONER INC if you see this review please contact me so we can sort this out like civilized human beings and I will send you the damaged ink cartage and please send me another one, and I will write a good another review as long as you deserve it, thank you for your time. For the people who are thinking about getting these I would spend a little more cash and get ones that have FULL ink in them, have a great day everyone!

I ordered the blue/black ink pack and it looks like a very light blue. Almost like its been watered down.

I have always like noodler's inks, and I have several colors. This is a distinct disappointment. While the base is supposed to be blue, after using on several different papers it is clear it looks like a darker green...not a bluish black like its described. If I wanted another green I would have bought more green ( I already have two other shades of noodler greens). So while it looks to have a pleasant dark blue base I am everyone else I have had look at it in various light and papers sees green. I looks like dark green blue base....but too much green to ever be a black. I wanted something for forms and job apps and you have to have a blue or black, and this is neither. I suppose I will have to try to mix in one of my noodler purples or buy a true black, which I did not want to do. A real disappointment in color name (and from description at noodler website). The correct ink noodler ink properties are there but the color isn't....and yes I shook the bottle, I have been using noodler inks a while.  This would be my 7th different color ( I have repeated a couple) so I know what I am talking about. So be warned if the color description is important, but functionality is fine, even if color off and not true to description.

Update 3/3/2017: I have had three more people look at this ink and they also say it green not blue black. This need to either have the color reformulated or to have the description changed. Tried more, different papers. I am stumped why this ink looks green not blue/black because when I clean my pen the washing water looks blue green. Speaking as an art minor, I think it needed a lot more black or blue pigment in the mix. I'm going to try to contact noodler and see if I can mix ti with their black swan or another color i same class to get a more black or blue color. This remains the only ink of their I am disappointed in.

Color is either a reddish-brown or a brownish-red. In any case, I'm happy with the ink, but not so happy with the bottle. The bottle opening is too small to insert your pen for refills. Best if you have an spare ink bottle you can empty into and use from there or else find your syringe and refill that way.

Ink flow is inconsistent, but the colors are great. I wouldn't likely buy again.

I was expecting something more vibrant, but it turned out it was like I print it out from my home printer. The colors were a bit dull for a wall print. I hang still hang it on my wall anyway, but it wasn't that eye-catching as I was aiming for a "beachy" ambience in my home.
