Trade: a white pencil. And a blunt one at that! This has gotta be the least used colour (if you can even call it that) in your tray of Derwents, hands down, and the most useless. A true #shittrade4shitmassage.. It's almost as bad as the licorice flavoured jellybeans in the bag, but I don't want to get into such controversial sugar politics here. And anyway, I don't even eat sugar nowadays cos I'm holistically woke AF.
