Review on 🖌️ Kasteco 2 Pack Art Ruling Pen: Precise Application of Masking Fluid for Line Work by Carol Miller

In theory this is a good tool for some environments. I wanted to use it to apply watercolors to create drawings. I used thin watercolors. Maybe thicker colors would work better. It's difficult to control when the ink moves onto the paper. I prefer DIPED CALLIGRAPHIC pens or CARTRIDGE CALLIGRAPHIC pens where I have much more control over how the ink flows from the pen to the paper, more control over thin or wide lines (nibs of different sizes) and callig nibs and pens to designing or writing. Right now my project is creating a colorful border around a 12x16 quote on watercolor paper. 11.3.2018
