Examples of basic pens you need for sketching. Uniball micro roller pen, Sharpie permanent marker, A pencil (I really like Dixon Ticonderoga pencils), a Staedler permanent felt marker, the Lamy fountain pen, Copic Marker, Pentel Signature marker, Koh-I-Noor Hardtmuth leadholder, and Rotring 600 mechanical pencil. Part of the KISS simple sketch tutorial. Vector Graphics (Adobe Illustrator) finished with Adobe Photoshop.
