The book form of the packaging was retained over the years, but details changed several times: on the Hemingway there was still a slightly removable sticker on the front; on the Agatha Christie the pen was fixed at the cap top and pen end with an easily breakable clip clamp under the silk cloth. Vertically embossed stripes on the book spine are original. Packaging is now also being counterfeited, which is why even existing original packaging is no compulsory authenticity proof; the evaluation must always include the writing instrument and the packaging together.
