The Pentel Multi-8 is an 8-function multi-pen or multi-pencil - in this case, pencil, because this Art Pencil Set has eight different coloured pencil leads inside one pencil body! Set with spare and extra colours, includes 12 extra refill leads, so you can swap out colours to better match your use, as well as having spares of the ones you're likely to use the most. Pencil lead pointer also included. 

If you enjoy coloured pencil drawing, it doesn't get much more compact and convenient than this.
