Beautiful colors easy to bleed. Tried using it with my circuit explorer air 2 and it fit good for thicker lines.
            

They work great!
            

Bought these for my son's 4th grade art project.  They were painting mini wood haunted houses.  These worked great.  The colors showed up well on the black painted wood and they were way cleaner and easier to use than regular paint.  The kids loved them and they survived being used by 27 9 year olds.
            

Good pens..nice to use...vibrant colors.
            

Although the pens themselves are much slimmer than I had expected, the color, quality, and intensity are remarkable! Just enough shimmer and it doesn’t rub off as I work, they are perfect for everything from coloring to calligraphy. I will definitely be getting these again when mine are spent, and as gifts for the artists in my life.
            

Ink bleeds but it pretty. Be careful when using
            

Absolutely love these markers from Ohuhu. Not my first product from this company. They are very pigmented and love the brush tips ease of use. Unfortunately I had an issue with one of the markers being dried out. No problem!! Emailed the company and they responded very quickly and resolved the issue. Very satisfied with these markers and company. Will definitely be purchasing from Ohuhu in the future.
            

Love them great color saturation
            

I love these pens. Work well on both drawings and gouache and watercolor paintings. I especially love the white one. It goes on clear but when it dries it give you a nice shimmering line!
            

Great for rock painting.
