Made with a 6B Venus pencil. I’m not a stationary fetichist apart from these pencils.
My mum used to use them in her job as a draughtswoman and got me hooked on the green crackled glaze.

Here’s Mario. Strawberry creams on top of sponge and chocolate cake.
A dark chocolate moustache of course.
A car cake. With sparkler exhausts. Jaffa cake wheels of course.
What was left.

Venus are totally the best! (But I confess I’m biased as my Dad used to work for Berol and I was spoiled by having them on tap as a child).
Love Mario!
