The color would suddenly spurt out and instead of a nice small dot or line you would get a big blob of color, ruining the project

You can have a better line with these

I highly suggest the extra fine because these pens are for fine lines etc and you won’t use as much paint

They are the fine line needed for detail work

Nice thin lines

Smooth lines, good quality paint.

The students love the line but a common complaint is the sputter they get.

Can get super fine lines

The markers are great to work with for fine line work and even to fill in smaller areas.

They dry quickly and leave a nice, crisp line

Nice fine line.

I use them for VERY fine lines in my paintings and to sign my paintings as well.

I pump the pen a lot before I start to draw I can get a rich thick line

so it's hard to get good clean lines.

Great for small writing or fine lines on the rocks.

Here are some of the rocks I painted...easy to get those wonderful fine lines and tiny dots with these fine-tip markers.

I was looking to create smooth thick lines

They are good for when you need a fine line and the paint brush just won't do it right

I bought these for fine lines and details on my rock paintings!

The tips are smooth, the line uninterrupted- the color vibrant, no odor.

Ive had so much fun with all the colors and love he control and fine lines and coverage

I use these for rock painting and are great for fine lines

I use them for my artwork and they give me consistent lines with vibrant colors!

Love love the bright and clean lines

I can do very fine lines and dots and the colors are nicely matched

The thin points made for very nice lines and allow for good detail.

These pens are perfect for writing words, fine lines and making dots

I use them for painting rocks and they are perfect for fine lines and detail.

I am really into nail art and wanted something that could give me extra fine lines

The only caution I would give is that you get the best and smoothest line if you 'pull' the pen toward you.

The fine point allows us to reach most small areas on a part as well as allows us to keep the lines nice and neat

Easy to use, nice fine lines of paint.

I recommend posca pens, but not the fine line ones

I have found that when I draw on a bump or uneven place on the rock , they splash, leaving a messy line, They also cant be used for coloring even the tiniest area

They deliver a consistent line, smoothly, and the nibs are not hard on whatever paper I am using.

They write good and you get a fine line.

The quality is just as great as any of the Posca pens - but the splattering is heartbreaking, especially when you want the fine line this can create, but it gets ruined

These were bought to do fine lines such as fur details on an animal with the medium of a painted rock, but the lines are much thicker such as that of a crayola marker tip, whereas i thought this would be as fine as a gel tip.

Able to paint nice fine lines with ease.

Daughter loves these, They give great color and a nice fine line.

They are great for fine lines and details

Others in the Rocket City Rocks encouragement rocks group suggested the fine line ones, so I bought these

They make super fine lines and the colors are great and flow nicely

These work great for detail work and fine lines

I use them for rock painting fine lines and they work great

They worked well on glass, plastic, cardboard and stone, and they can make nice fine lines which would be hard to achieve with the finest brush

These are a must have in the grab bag of supplies for fine line drawing

I didn't relize they would be fine line

Nice fine quality line

I paint rocks with these and the extra-fine tip is perfect for writing words and drawing fine lines

I bought these for painting rocks, for the fine lines

It is possible to do a very fine line, unlike my other paint pens.

I purchased these to make fine lines on my rock art

Great for rock painting, makes a very fine line.

You still have to push down hard enough to compress point back up into the barrel to first get the paint to flow, but unlike every other brand, instead of partially dulling and rounding out the nib, you have a very fine point that you can use to either make precise lines and dots or go over an area more for wider effects

We had gotten some fine point that did not work as well but these are great for fine lines and writing on rocks

These paint markers work beautifully with precise fine lines and vibrant colors, but the packaging and pens themselves are exclusively in Japanese or Chinese (I won't assume which language)

Pens leak when you are trying to draw a fine line.
