I bought this pen set because of the color range and 0.5 tip, however these pens scratch paper and don't write smoothly. I didn't return them because there are a few great colors that I use frequently in my bullet journal.

Faber Castell makes excellent pens, but I didn't realize that there were so many repeated colors in this set.  I wanted as much variety as possible, and may not have read the fine print as carefully as I should have, but the selection was a bit disappointing.  The set is rather expensive, and I might have done better with two different smaller sets.  I was using them for travel projects while traveling in the car, so the single box looked efficient.  Read the color selection carefully!!!

These are amazing pens for my BUJO habit. Unfortunately some colors don't seem to work as well as others...it's as if they're dried out or something.

I like the blue best but have to use black where I live. I have to try my refill cartridge next.

I receive  those Nupastel colors but some of the colors are not blending or appearing on the paper as they should. It sad to know I can't use them as I should.  When i try all it does is leave mark or spilts the paper.
I really do need those pastel for my art class.

I love that the background is clear. They are small and make nice accents for a bullet journal. The images aren't the sharpest, but they still look nice.

The colors are vibrant and rich. Maybe it's just a function of cartridge size, but the color cartridges don't last very long, which is frustrating.

I was worried they would be too dark, or bleed through my textbooks.  They don't do that. The colors are diverse- none of the colors look alike on paper (the 2 blues are very different from each other, the pinks/reds/oranges are very different)

These colors are beautiful. They do bleed a bit through the paper (textbook paper and copy paper are what Ive used them on), so if that bothers you, don't get these. Other than that, they are high quality and a fun set of highlighters for when studying gets boring.

Great variety of colors not usually available in in-store packs.

I ordered these to try bullet journaling and they are holding up great! I love that I can flip the cover and view just one page at a time (many dot grid notebooks are bound and thus limit this ability). The paper is a good quality. I do not use fountain pens, but think there may be a chance of ghosting or bleeding through the page, as sharpies and heavy use of brush pens has left me with some ghosting in a few places.

I must confess I did not buy these because they are "Green" but because they are a light color; so many post it notes are a very dark color and/or bright.  Reminder notes need to be easy/fast to read and a lot of bright colors lose the attention-getting purpose of one bright color among regular colors.  I did not mind paying a bit more for what I wanted, with "Green" being a bonus.

I have used several BIC multiple color pens.  In my work I needed red green blue and black.  Pencil & stylus would have been nice.  The way my pens disappear from my desk made $40 pens vanishing rather annoying.
Hence I bought many BICs only to find that on most pens the green did not work.  After green the red stopped working.  Blue & Black lasted until the pen was stolen.

I bought this journal so I can freely write and doodle without the restrictions of lines. I decided to get the journal in black. The pages are unlined and thicker than normal notebook paper, however, I do not think it would hold up well to paint, sharpie, or markers. The journal itself is extremely well made and has held up to my daily use over the last few weeks without any rips or scratches to the pages or the cover. I especially love the band. It makes it easy to keep track of my pens and pencils as I can just tuck them in, place the band on the notebook, and they'll be held in securely.

If my review was helpful at all, please mark yes!

Getting into using these. Some have a great flow, others scratch the paper a little. They do not bleed through on my bullet journal so I will call that a win.

I love the colors, but there is a rough sort of texture that causes bumpy lines when drawing on it with gel pens or markers, and that is what I purchased them for. Oh well, I will use them for other things.  It is a high quality card stock, don't get me wrong, just doesn't work for my purpose.

Great pens for bullet journal.  Nice variety of colors.
