Well, "Writing titles, sounds, onomatopoeia, headings, decoration, and word art pens" is the full title, but that's too long.

I made some more writing pens! I wrote the English names of some pretty flowers for examples below. In (parentheses), I'll write their names for anyone using Microsoft Translate. :)
Please adjust the settings like stabilization to your liking!

Sway Calligraphy has an S shaped tip. It's fun for Big Capital Letters that go "swish". (Saffron, Crocus sativus)
Rhombus Calligraphy has a rhombus tip. Great for sharp letters & curves, adjust the angle & pressure as needed. (Rhododendron)

Round Square Outline is, well, a square with round edges. These are great for postcard writing. (Rosemary, Salvia rosmarinus)
Square Outline is the same, but sharper. Both are affected by speed, but not pressure. Feel free to adjust it to your liking. (Senecio)

Halftone Writer 1 & Halftone Writer 2 are two dual brushes that have halftones on the back. You can change out the halftone texture for a different pattern if you'd like. (Hellebore, Helleborus) & (Hollyhock, Alcea)

Halftone Writer Inverted has a solid outline. I think it's easier to read. All 3 of the "halftone outline" pens overlap no matter what, so it is best to write all characters in one stroke. (Hazelnut, Corylus avellana)
The Dirty Halftone Writer is a rough pen for rough jobs. Great for Zines! (Dahlia)

The organic writer is another rough pen. It is perfect for small, scratchy writing, or line art. (Osmanthus, Osmanthus fragrans)
The Square Brush Writer is a brush pen with a square edge. Dry & organic, fun to write with. (Snapdragon, Antirrhinum majus)

The Chisel Marker Writer does not have any pressure applied to it. Feel free to add pressure if you'd like. (Chinese Peony, Paeonia lactiflora)
2 Color Overlap is your standard shadow writer. This one is thin & made of 2 tiny triangles for a sharp, modern look. (Columbine, Aquilegia)

The Groovy Writer is another textured writer. Feel free to change the texture as with the last one. (Godetia, Clarkia amoena)
The Bubble Writer has no pressure & gives an even line of circles. You can also use it to make pearls or beads. (Baneberry, Actaea rubra)
The ones below are for sound effects/onomatopoeia specifically, but can be used as general decoration as well.

Electric Buzz & Zap Writer are for electrical effects, and the Knife Dagger Writer is great for scratching and horror effects. See what works for you.
I sadly have not tested these with any other language, as I can only write in English, my apologies. Hopefully they'll work for other writing systems too. Most work for drawing weird line art, so don't feel limited to just writing.
