There aren't any.
Let me back up.
So, many of you don't pencil with graphite pencil that requires erasing afterwards. Many of you use blue pencil, or red, or whatever. Because we have scanners now you can use just about any color you want to. Well anyway, one gripe many have with colored pencils and colored mechanical pencil leads is that if you DO want to erase them, they don't erase well, if at all. The reason is the wax binder they use. You can buy the fabulous Prismacolor Col-Erase pencils, but if you're like me and you both loath pencils and prefer lead holders, you're SOL because they don't sell just the leads, they only sell pencils.
Well you know me, that just wasn't going to do at all. So my first thought was, I'll just split the pencil open, carefully remove the lead, and put it into my lead holder. Well, getting it split open worked great...
a whole bunch of leads in various unusual packages, including this flippy door one,
In the meantime, my great thanks to Alberto, you are too generous!
Oh, and it looks like someone tipped Jesse off about my attempt at fundraising for his podcasts. Thanks, whoever! See you next week!
