This very professional alarm sign and sticker set tells crooks to go elsewhere! The weatherproof pvc sign is riveted to an 18 inch aluminium post . The six decals should cover many windows and doors to help send the message that this place is not to be touched. I designed the sign and it is manufactured by largest manufacturer in the country. I personally inspect each sign before I rivet it to the post. I also inspect each sticker before I slip it into the.package. I care about my product and I care about you. Stephen
