Zensations Brush Pen, Black, 0.3mm, 1-Pack | Japanese Design, Creates Thick and Thin Lines in One Expressive Tool, Water-Based Pigment Ink, Ultra Fine Tip (01111)

Really cool pen for inking comic/cartoon art. The variable line weight is really fun to experiment with, though there is a bit of a learning curve. It's easy to have wibbly lines if you're not confident in the stroke. The action is fantastic though, especially considering it's $3 or thereabouts. Important note though, they do need a second to dry, like, you need to make sure it's definitely dry before putting anything on top. I was trying some brush markers over the lines, and it ate the parts that hadn't dried yet. That's on me though, more than the pen. Great stuff though I'll definitely buy them again

one of the best brush pens I have ever found

I have tried SEVERAL different brush pens and found that this held up the best and made it easy when practicing doing hand lettering/calligraphy. The tip is perfect size, easy to control for various pressure points when writing and it's a light weight pen. I highly recommend this!

Great pen, BUT not as waterproof as claimed. When I went to put a brush coat of isolation coat over it (on Golden fluid acrylic paints) it ended up wiping off. I stopped the moment I saw it happening and did a spray coat of varnish before continuing. This was frustrating though since I generally want to do isolation coats on my works. Good thing it was a practice piece! Unsure if it might have a different result on watercolor paper, but definitely test it before commiting to anything major!

I love this pen. It lasts forever and is great for line variation for art stuff.

The ink flow is amazing and I barely struggle with leakage like from other pens I’ve used! It’s fun to use and it is definitely worthwhile id recommend it!

Performs great for thick/thin lines while also maintaining a firm nib

I really enjoy this pen for brush calligraphy even more so, surprisingly than the Fuedeno type brush pens. It glides so smoothly, and has a firmer flex (I tend to be heavy handed) so it’s perfect for me for calligraphy.

I love this fude (brush) pen. Got it for practicing my Japanese kanji and kana. It has a fine even tip that it doesn't mess up smaller writing.

Nice quality pens,lovely writers, good price and fast delivery.

Rich black ink. The tip is firm so feels more like a fine marker pen but writes beautifully.

Such a nice pen and worked with watercolour with no running :)

Smooth writing, doodling, too.
