If you’re in the UK you might want to tune into BBC Two next Tuesday (19th March 2019).
The Inside The Factory series will visit Faber-Castell’s pencil factory. If you cannot wait you can watch a little preview on the BBC’s website.
The BBC seems to be rather keen on Faber-Castell. They also had some of ‘their guys’ working in the Faber-Castell factory for a previous BBC Two show and had a look at Faber-Castell and Staedtler for a previous Radio 4 programme.
I believe that showing the preview clip from BBC Two’s Inside The Factory in this blog post falls under “fair dealing” as described by the UK Copyright service.
