Paper Scrap

A paper scrap is a new trash item introduced in Animal Crossing: New Leaf. It is obtained by not filling out (or taking too long to fill out) a Petition Form issued by a villager. The villager will say that the player took too long to get the signatures for their petition and that they had to send the list already, both canceling the request and turning the petition form into a paper scrap. This item has no use and is considered trash. It can be disposed of at Re-Tail for 120 Bells or thrown away in a Trash Can.

Trivia
Waiting for a villager's petition task to run out of time is the only known way of obtaining a paper scrap in the game.
