A darn good 25-cent mechanical pencil

Carla ordered these cheap Bic mechanical pencils. I tried one out and I actually like it a lot. The lead diameter is 0.9 mm and it has a number 2 lead inside. It also contains one extra lead in the barrel. A 24-pack sells for about $.25 a pencil. They are supposed to be disposable, but why not buy a bunch of 9 mm lead for cheap and keep using the pencil? You can even get colored leads!
