Our sticker kits help make your care packages more personal! Dress up your box flaps quickly and easily on the inside. Each kit comes with 4 large adjustable stickers designed to fit a USPS Priority Mail Large Flat Rate Box. Please note the kit DOES NOT include the actual box, only the stickers. Boxes can be picked up for free at any United States Postal Office. The stickers can also be easily trimmed to fit a USPS Priority Mail Medium Flat Rate Box.
