These Halloween pens are a perfect giveaway for trick-or-treaters! Hand them out at a trunk-or-treat event or a Halloween party and encourage young ones to keep them around their neck like necklaces while they're trick-or-treating. Costumed kids can use them to cross out the houses they've already visited on their Halloween tour of the neighborhood! Black ink. Plastic. 5" on a 30" nylon cord.
