Well, the let's try the Argentine way: if you don't have any A9; A8; A7, A6, A5; A4; A3: A2 pencil you ask any kid in your =neighborhood a small rest of an HB pencil.
It will neet slightly m,ore presuer but will work fine.
Eventually you can san a bit of the point and use the powder as you would use graphite powder.
If also that is not possible find in your toolbox the rest of that carpenter pencil you bnougfht nineteen years ago and sand a b it of it's point.
If your tool box is not findable take any old pencil you have and try it.
If none of that is possible send your friend Daniel Caso in Amsterdam a P.M. through this forum and he will be pleased to send you an A9 pencil by the post.
Daniel
