Mechanical Colored Pencils

A few years ago, a friend of mine (I forget which) has been written on a piece of paper and I noticed it was written in red (not black / regular color of lead) with a mechanical pencil. She said she had lead color (or graphite) which enabled him to write in different colors depending on the color of the head she had.

I just remembered this recently. Now, I'm interested in this kind of lead-colored, but I do not know where she got it.

Does anyone know where they sell leaden 0.5 mechanics?
I have lots of pencils and I could use color to lead to fire without having to use crayons.

Hmmm ... I think they are red like a pencil control ... But Im not sure of other colors. red can be found at Staples ... or any store larger offices

Probably a dollar store or a store where you can find regular school supplies, such as lead.
