This is a case of 20 pencil leads suitable for Uni-ball Kuru Toga mechanical pencils. The lead has a special composition: a soft outer layer around a harder inner core. As a result, the lead can be easily shaped into a point, which is what Kuru Toga pencils are uniquely designed to do. The lead case comes in various colors, and the slim profile slips easily into your pencil case.
These refills work great with the Kuru Toga Pencils. I just wish the Kuru Toga
would use more of the lead up. It always leaves about 1/2" left that I cannot
seem to use since the mechanism will not rotate this small piece remaining.
Excellent lead for the Kuru Toga pencils. Has an excellent quality of lead. Does
have a better wear pattern (slightly) than normal pencil lead so I would say it
is worth it if you have many rotational action pencils.
