One for puzzle-lovers, this Tornado mechanical pencil celebrates the humble crossword, with a design inspired by the familiar black and white puzzle grid on a lacquered steel barrel. There's an eraser-tipped knurled twist-action button at the end, to extend the lead, and a slotted metal pocket clip. It's supplied with spare leads and erasers in a vintage-themed cylinder which doubles as a pencil stand as well as a protective case.

Refill with 1.15mm leads.
