The book product is different from picture: the cap is all black with no orange button. If I had known, I would control elsewhere because this all black model is also available elsewhere for less. Otherwise I have found the Plumix, the pen is very steep, hangs slightly but I like the use. When I feel like for a more flexible and pen that glides better, j uses a LAMY Safari but I delight in alternate. Furthermore the end Plumix al Advantage really write end.
