The Journal of Smells is a tundra-sized leather-backed journal which Mira uses to keep her notes. It has a small button on its front in which a leather thread can be tied around it, keeping the journal closed. It's front also have little doodles etched into it, all of which are of Mira's design.

Each new 'chapter' of the journal contains a new smell. The smells in Mira's journal include, but are not limited to: crushed flowers packed into teabags, pieces of cloth doused in perfumes of varying scent, sealed bags containing random fermented stuff, and the leaves of various plants.

Leather, paper made of sugarcane.
