MONTANA COLORS WTF PRIORITY MAIL STICKERS
WTF stickers are permanent, customizable stickers that are suitable for outdoor use due to their excellent adhesion to various surfaces and their strong resistance to water. The "egg shell" composition makes them almost impossible to remove. They break into thousand pieces! The WTF 'Priority Mail' Stickers are based on the USPS (United States Postal Service) priority mailing labels. These adhesive labels have become a very popular tool for sticker bombing in the United States.
