In early 2008 PANArt created a booklet that offered insight into the various phases of the Hang’s development. It also introduced the Integral Hang, so a printed copy was given to all new buyers. For this information to become available to a wider audience, the Hang makers have now authorized the Hangblog to make the booklet available online as PDF.
It is published in five different languages: Englisch, German, French, Spanish and Italian.
