Yo so while I haven't picked one up from AP yet, I've used these bad boys for quite some time already and here's the deal: the sandwich nib plates really do give you the cleanest edges and sharpest lines I've seen on any portable calligraphy tool. The ink free-flows in between the plates which means that it will put out a lot of ink depending on your speed and style so just know that more fibrous and course papers will bleed a bit at stop points. But on anything like parchment or Bristol and you're good. These are well balanced (a lot like a larger quill) and super portable. Also super low maintenance, easy to clean, and with the way you change ink cartridges allows you two ways to blend: 1) you can flood the reservoir behind the nib with one color and then load another color refill behind it for a gradual transition, or 2) you can touch the nib to any other ink color and it will draw a small amount in for small sharp transitions. Either way pick one up for sure to play around with because I've been paying $14.99 and art stores for these baby's and AP is out here takin hits at $7.99 just so you kids can do art.
P.s. You can use the small edges of the nib for small detail work, I think it's .3mm
Got one of these years ago at the flea market,and it was streaky as f*ck no matter how much i juiced the nib or shook it up,could not even write one smooth letter,was the worst 15mm marker I ever had and I have had pretty much every 15mm u can think of.it was the paint inside that sucked,the marker on the other hand is decent.by the way I got the lime green one,and yea it sucked big time,maybe I will try a different color like silver,gold, or copper next time.
These Pens are pretty dope . They come in in bigger sizes which I prefer more so over this particular size. Like 6.0 . They have helped hand stylez . Very fun to use . And they have many different colors for the refill cartridges . Overall probably one of myfavorite pens ever. Besides the Sakura calligrapher and the other Sakura chizel tips
