A trick-or-treat bag (also known as a trick-or-treat pail) is a commercially produced bag or pail that is intended to be used for trick-or-treating. People put candy and other treats into the bags or pails that costumed trick-or-treaters carry.
Pillow cases, beach pails, tote bags, shopping bags, messenger bags, backpacks, and fanny packs may also be used by trick-or-treaters instead of specially produced commercial bags or pails.
