Pretty good, just be patient with it on the first time applying it.
Works well, just be sure on the first time to shake it really well and press down on a surface for the paint to come out. It'll some time so be patient and it'll work a treat.

Super useful marker
These are great markers! For those complaining about them not working all I can say is they're obviously not using them correctly. When you first get it, give it a good (but gentle!) shake back and forth. (There are images on the label showing you what to do). Then you need to get a scrap piece of paper and push the nib down and release, down and release. I had to do this a LOT before the paint fed through. You'll notice the nib starts changing colour slowly from the top down to the point - gently keep pushing the nib down and release which feeds the paint from the pen to the nib. Once the whole nib is saturated with colour, you're good to go. Before each use you need to give it a gentle shake and push the nib down once and release. No problems. It writes smoothly and gives good colour coverage. It's a water based paint so it can be used on glass etc and will wash off. I use mine in a journal with Tomoe River paper and it's a dream to use.

Is great for graffiti on smooth areas.
Is a great product I love that is actually writing with paint and not ink however I don’t like it that the paint easily scratches off.

CANNOT GET THE LID OFF....
I wanted to go over a few dark marks on my old blinds - but its still sitting on the shelf as I can't get the lid off. [ Having searched for instructions - which seems ridiculous but there it is]. So I cannot get the job done I bought it for.

- I would hate my life if i didn't have Posca pens
I am a professional artist. - I would hate my life if i didn't have Posca pens! These pens are 100% the best of their kind. The tip is soft but not so soft that it breaks away after a few hours of use, the depth of the black paint rivals ink - which anyone painting on canvas will know is as dark as you'll get. They're lightweight and super versatile and whats best is you can draw with the nip pointed upwards (like on the ceiling etc) and the pen's fluidity isn't effected. i've used these to paint: Canvases Brick walls Windows Cardboard Put basically, it's paint in a pen that will write on anything..

Excellent pen
Excellent thick marker--great coverage, only needed to use it once for each line. Nib was chiselled, one end thick, the other slightly thinner. Very happy with it.

Mi idea era usarlo para las orillas de los accesorios de resina pero no me gustó mucho como luce, es un poco como oro viejo, en cambio en el papel luce super bello

Deze krijt stift werkt heel goed. Even duwen op het punt, zodat de vloeistof het punt van de stift doordringt en daarna vlot schrijven op het bord. Fouten wrijf je gemakkelijk weg met een doek. Prima product.

This worked perfectly for my "draw your own wallpaper" project for my home office. The tip did get freyed quickly but it didn't affect the application much. I had drawn my pattern in chalk first and the chalk dried up the tip of this marker making it a bit difficult, I had to keep wetting/cleaning the marker, recommend using very light chalk line or something other than chalk. Overall very satisfied, this project used up about half a marker so it goes a long way! Very satisfied.
