As a comparison, here is one with the easy-peasy-to-control Tombow (and a gel pen, prompt "frail"):

@danielerossi Okay, that one does not have any special way to control the ink flow amount. (The one on the left can control it by squeezing.) My guess is that it just wasn't flowing steady on your first couple of goes and is now working as intended. I store mine tip up, and it still flows like mad from the moment I start.
The pocket brush is crazy sensitive as previously mentioned. You can do what Vivian mentioned and just wipe away excess, or do what I do and embrace the fact that lines will come out on their own terms. "Happy little accidents!" That brush is a bit like watercolor, in that it adds variety whether you like it, or not. I've recently started playing with using short, animator type lines, to give it even more unpredictable life!
Here's an example of one of my favorite pieces from a recent sketchbook full of elephants using this technique (prompt was "tired"):
Day 9 "Swing" and also the last page in my 100 Elephants sketchbook! Learned a ton doing this 100 somethings challenge. If you'd like to see the drawings go from utterly terrible to definitely not as terrible, I made an insta story with the whole process. https://www.instagram.com/stories/highlights/17843775202658463/
I thought I had a pretty delicate hand with pens and pencils but those brush pens are on a different level of difficult
You can't truly understand @Jake-Parker 's reference to drawing with "butterfly kisses" until you've met the Pocket Brush.
I decided to do the "5k" this year and do 1 per week. My focus is on painting right now and Inktober is just so time consuming. But I still want to participate and put out something worth looking at, so I compromised with the 5k. One (maybe 2) per week should be doable, and I've been using this month to slowly work out the sketches so all that needs to be done in October is the actual inking.
