Sun-Star is a Japanese stationery company that plans, develops, manufactures and sells stationery and gifts with interesting and new design concepts.
 
The Nocfree is an automatic-advance pencil - a mechanical pencil that feeds the lead automatically, without you having to click the button. OK, clicking the button isn't hard, but it's a little distraction you can now do without. Great for taking notes, without risking missing a bit because you had to stop to click out more lead.
 
It may be that very Japanese thing of solving a problem you didn't know you had, but these things can be surprisingly helpful when that tiny problem is taken away.
 
Please note the lead is a black colour.
