It's an extremely simple locator charm.
A simple rune, plus a low-quality talisman paper — whether it's torn or wrinkled, it doesn't matter — there's no need for complex structures such as symbol feet or symbol gall, all it takes is injecting a tiny bit of magic power, and that's enough.

During the snowfall two years ago, some jerk transformed a 'smelly snowman' whose snowballs reeked... Geez, it was a horrifying sight."
