Kuretake brush pens in my new case.

I've been asked what is Kuretake, which one I use in my drawings.  I use few kinds, Twin, Brushables, Real Brush, water brushes H2O, Kuretake 13, Cocoiro  Letter pen. I like to take Kuretake brush pens with me in this roomy tall pencil case from JetPens. Here is few different kinds, some dual points, some bright, some muted colors. Looks different on different paper. Still a lot to try and experiment.
