I saw  ecmajor post about working tools and I thought to do a similar one. I love drawing tools and I'm always curious about it.
Mine are: HB Pencil Faber Castell, to be consumed until the last fragment with a pencil extender. Caran D'Ache Prismalo and Swisscolor, I like Prismalo better because they're dryer and I work better with dry colors than soft ones. Windsor & Newton and Talens watercolors, I find Talens slightly better, pigments are brighter. A local brand of brushes, Borciani-Bonazzi, cheap and very good. Eraser cut in stripes to reach the most hidden places of that damn DIRTY drawing.
