I remember the first time I saw two-color pencils.  I think I was eight or so and thought they were so cool!  These pencils, by venerated house of writing implements, Mitsubishi (but not related to the behemoth multi-national companies that make cars, offer banking services, own Kirin beer, etc).   Back to the topic—these pencils are great for editing, drawing, impressing eight-year-olds, you name it.  Sure to please!
