Taotree 36 Colors Bullet Journaling Pens Set, Fineliner Colored Sketch Writing Drawing Pens, Porous Fine Point Pens Markers for Planner Note Taking Calendar Coloring Art Projects, Great To Art Crafts

These are great waterbased Fineliners. The .38 mm tips are my favorite size for small detail work in coloring books and for doing Zentangles in Color. Also work great on top of acrylic paint pens (for mixed media).The colors are really juicy and flow smoothly across the page. These colors also layer/blend with each other.I love that they come packaged in color groups and that the case, while plastic, folds in half to give you a 5x5 or 6x6 square that easily fits in a purse or backpack. It seems pretty sturdy. It also has the colors and a swatch on each side, so it is easy to keep them organized when you put them away.Each pen also has its own niche, so they don't wiggle around and get out of order.The caps are not round so you can take out several colors and not have them roll all over the place. The pens are also thinner, which I found very comfortable.One pass of color is true to the cap color, but if you go over it again, you will get a tone or two darker. Beware that if you do that on cheap computer paper (which my swatch is on) it will not unexpectedly bleed through. So it is not a good idea to do that with cheap coloring book paper or lightweight computer paper stock. You will want to use a blotter sheet between the pages and not color on a book that has an image or writing on the next side. Again, this is with cheap weight laser printer paper. You will be fine with a light to medium cardstock which most adult coloring books (Colorit is one) use, and also most bullet journals are made with a thicker paper.They match really well with TaoTree' 32 Glitter gel pens. (see my review there).About 90% of the colors match the color on the cap and ends really really well. The executions are light yellow (which is more of a light gold brown yellow ochre Grape Purple and Light Purple, which lean more towards a brown). I think the Violet, Purple and Florescent Purple fill Purple needs, and the need for a yellow is filled by Cadmium Yellow and Florescent Yellow. One trick I learned is to get some .23x.5" laser jet lablels and swatch out gel pens on them (as they Never match their caps across every manufacturer). I am going to do this for the light yellow,Grape & Light Purple and stick the lable on the cap. I do this for all of my gel pens and some other marker and pencil manufacturers.I am very happy with this purchase and would recommend them to others. If the manufacturer made the exact same set with a .7 or.8 nib I would buy it as well (though I would hope they fix the 3 "off" colors it wouldn't be a deal breaker.In the swatch photo, the lighter half is one pass with the pen and the darker is two

I was surprised at how well these pens blend-- being water-based, they are capable of blending, but even my leagues more expensive water-based markers don't blend half as well as these do. The blended color also does not last, and nigh instantly wipes off as soon as you start drawing again as evidenced by my yellow pen being completely unstained by blending with orange.The colours themselves aren't heavily pigmented and due to the nature of the pens will oversaturate, darken, and start destroying the paper if you keep layering them, but as they're pens and not markers you probably really shouldn't be doing a whole lot of layering or colouring large areas with them anyway.As for the colours-- it's not a huge deal to me, but to people who absolutely love having a wide, pigmented range, this may not be the best bet. The variety is good, but not nearly as wide as I've seen in my years as someone who has a mild obsession with markers. Some of the colours also don't lay on as thickly as, say, the standard red or blue, and make anything that's not just writing a bit difficult. This is a common thing with markers and pens, so I'm not too bothered.Would love to see a marker set from the makers! Just something with a larger tip that could be used for more extensive colouring in things like colouring books would be absolutely amazing.For the price-- it's unbeatable. 36 pens for 13 dollars? My much more expensive Tombows were about 17 dollars for 12 and don't work half as great with blending as these do. The look of the pens is also stunning and they'd make a great addition to any artist's repertoire, or even just as a gift for someone who likes doing things like scrapbooking or journaling.All in all, good product. Definitely deserves the rating.
