Mine was received through the basic subscription box, but it functions beautifully! Priming it into the cap is brilliant. I was concerned about ending up with an inky mess but it has a clean flow onto paper (the only medium I've used it with thus far) and very easy to control where the ink is going.
The chisel tip definitely gives a wide variety of line thickness and it's so soft it almost feels like a brush as i'm gliding it over.
The only thing keeping me from giving the full 5 stars is just i haven't experienced refilling the marker yet. It does seem like it will be easy, but I wouldn't want to mislead buyers before I know for sure.
I did try to see if this was available in other ink colors and it doesn't seem to be (at least at a quick search.) and i would love if i'm able to clean it out well and refill with various colors.
