These belonged to my brother when he was in primary school. But being the "artist" in the family, I naturally inherited them from him.
Staedtler is still making these - look at their website. Interestingly, they are classified under "Toys". Look at how their front sailing scene artwork has changed since 1984.
Appears that Brown and White were popular colours with my bro.
Ooooh tips on colour mixing and shading in the back of the box.
And a place to clearly mark your property.
The side of the box shows an outline of a pencil and indicates which end of the box to open to get to the pencil tips! Hmmm so well thought out.
