Pentel Artist Brush Sign Pen - Ultra Fine Tip

Very good product

Now these are great. Good immediate ink flow, good control of width. The ink is not really ‘washable’ with water…I dunno if it’s supposed to be but my experience is that it’s effectively waterfast when used in a big mixed media work.

This is my dream pen - five stars! It’s so easy to use, yet has the brush pen flexibility I’ve been searching for.
