Features: size and opacity depending on stroke speed – fast stroke is more thin and transparent, but it always has a little bit of ink on stroke start.
Recommended style: Better draw by fast short and straight strokes just as commonly used in drawing with a real pen
Palette: Ballpoint pen has 3 factory colors: blue, red, green.

Mechanical pencil
Mechanical pencil is the digital-analog of classic Japanese mechanical pencil. This is a thin line pencil.
Features: size and opacity depending on stroke speed but lines are more uniform than ballpen’s line. 
Perpendicular angle makes the pencil less sensitive to canvas texture.
Recommended style: Good for hatching, cross-hatching, scribbling, and also for long straight lines.
Palette: 2 hardness presets.
Example image:
Colored pencil
Colored pencil draws granular wide lines.
Features: opacity depending on stroke speed – fast stroke is more transparent. Very sensitive to the brush angle. The parallel 
angle gives wide strokes, the perpendicular angle 
makes the line bolder.
Recommended style: It’s good for fast hatching and shading. You can hatch without lifting a pencil.
Palette: Color pencil has its own color library.
Example image:
Classic pencil
The classic pencil is a flat shading pencil.
Features: opacity depending on stroke speed – fast stroke is more transparent. Very sensitive to the brush angle. The parallel angle gives wide strokes
Recommended style: Good for fast sketches and shading.
Palette: 5 hardness presets.

Metallic gray pencil
“Metallic gray pencil” is a simple pencil with a square lead.
Features: size and opacity are a little bit depending on stroke speed. This pencil gives more stable and straight lines than other pencils.

Palette: 5 hardness presets.
Example image:
Thin-Line Black pencil
“Thin-line black pencil” draws granular wide lines like a real long lead pencil.
Features: size depending on stroke speed – fast stroke is more thin. Very sensitive to the brush angle. The parallel angle gives wide strokes, the perpendicular angle makes the line bolder.
Recommended style: It’s good for fast hatching and shading. You can hatch without lifting a pencil. This pencil is very similar to the “Colored pencil” but gets narrower with faster strokes. Also, “Black pencil” ignore canvas texture.
Palette: 5 Hardness presets.

Marker pen
“Marker pen” is the digital-analog of watercolor marker pen. It has flat wide lead.
Features: opacity a little bit depending on stroke speed – fast stroke is more transparent, but it always has a little bit of ink on stroke start. The perpendicular angle makes the stroke thinner and bolder. Blends colors like a watercolor brush.

Palette: 3 graphite presets:
4B – and not depending on canvas texture. Has own texture.
2B – has its own texture but depending on canvas texture.
HB – depending on canvas texture, but don’t have its own texture. So this preset looks very different on smooth paper.

Recommended style: Smoothing and blending any art-styles.
Palette: 3 presets:
6340: Smoothing with the current layer and transparent pixels, and erase a little bit
6341: Only Smoothing with the current layer and transparent pixels.
6342: Smoothing with all underlayers and canvas, also, it has some transparency reduction limit for every stroke.
Example image:
Soft pastel 
“Soft pastel” is a digital analog of oil pastel.
Features: The perpendicular angle makes the stroke thinner. Blend colors.
Recommended style: Soft painting with visible texture.
Palette: “Soft pastel” has its own color library.
Example image:
Hard pastel
Unlike “Soft pastel”, “Hard pastel” is more like chalk
Features: The perpendicular angle makes the stroke thinner. No blends colors and give more texture unlike blending tools.
Recommended style: Adding texture
Palette: “Hard pastel” has its own color library.
Example image:
Highlighter
