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.
The case is slim and easy to store. I love that it is pink. The lead is just as
good as the case, it pretty sturdy and I am able to press harder on the pencil
when need be. Other leads I have done that with break.
