This is such a neat idea.... and very environmental friendly.... Only thing is i haven't used a pencil in ages.... needless to say a pencil sharpener..... And also i wonder how well the eraser would work..... Wouldn't the bits n pieces include the lead as well...?? What is an eraser made out of anywayz.... and how does it work?? hahahha so many questions...
