Caran d'Ache Graphicolor Highlighter/Pencil
Caran d'Ache Graphicolor BiColor Pencils feature a split core that is either graphite on one end and colored pencil on the other, or colored pencil on both ends.
These two-tone pencils have 0.3 mm cores. The superior-quality HB graphite lead is ideal for making annotations, and the watersoluble red pencil is great for corrections. The fluorescent yellow colored pencil can be used for making permanent underlines.
