You could also try looking for the colored leads in the other standard sizes. I've seen many different colors at the office supply stores. Not sure of composition of the 'lead' so might need to do some testing. I love the Bohin pencil! I've not tried the green though. I'd want a bunch of different pencils anyhow just because I'd be too lazy to be changing lead all the time! And yes, I use a regular mechanical pencil with #2 lead to mark on white fabrics. So far, so good with it coming out in the wash.
