The smoothest and darkest pencil . I rember when started writing I used this pencil till date when I write my poems and thoughts it make me go deep into my thoughts and I just cannot stop myself its like going into a whole another world . It doesn't hold me back and I don't have to sharpen her when I am lost in my own world . Its like this pencil helps me to enjoy my thoughts . I love this pencil and I will suggest you to get it and try it for yourself . I always get the whole box its come with a free sharpner and eraser inside the box .
