These brush pens definitely have their pros and cons.

Pros:

-Excellent Blending (with water & the other colors)
-Great Brushes (that are not too soft or hard and they're not imitation foam brushes)
-Light Weight/Travel Friendly (I take them anywhere and everywhere)
-No Odor/No Mess

Cons:

-No light-fastness (this is a HUGE deal-breaker for me)
-Not meant for large artwork (painting an entire 8/11" page will be T-E-D-I-O-U-S!)
-Little Ink (For the price you would expect the chambers to be full of ink!!! If I knew
that these were just glorified markers with brush tips on the ends I would have
just settled for Crayola Brand.)


Final Judgement:

These pens allow me to PAINT (actually paint!!!) without the mess and can be used/taken anywhere. While I have my complaints about these pens, I cannot put them down!!! Although these pens will not fully replace an actual water color and brush set, they are so convenient that at the moment I use nothing else!!!

I've been buying these in the 5-pen sets. Since I can't spring for it all at once.
But I have most now and boy do I love them.

I love the water-based media and since I like to bike and move around alot I bought these. They let me paint spontanesly whenever I break at the park, without the fuss of using a cup of water and brush and pans taking up room in my pack. (Now I can carry my extra snacks _3)
I like how you can dilute them simply by dipping them in a bit of water, how brilliant they come out, and the small sets are beutifully matched to eachother, and they do blend well.
They don't replace my watercolors entirely, but for the artist on the go they are fun and really worth it.

I bought this one to try out before getting the whole set and after the first stroke I wish I had the whole set. If you have used Akashiya's Fude disposable brush or Pentel's pocket brush, this is the same feel. The Pentel brush has more width diversity but that one has longer bristles. It looks really good even before you put water on the ink. If you do watercolors or brush painting this is a good buy. I gave it four stars for not being refillable. The length of the brush is really a good compromise, long so it has a larger ink capacity but not so long that it does not fit in most pockets and needs a special case.

i work in water color and inks, and these brush pens are not only fun but have brought a whole other level of style and look to my art work that i just love!

love them!!!! there the best and this is my first time using watercolor pencils:), if anything the color is amazing the tips are fine and prefect! and they can work with any medium!!!

tip- they work very well with copic markers and ink pens:)
