Question Authority Bumper Sticker/Car Magnet * 3" x 10" or 8cm X 25cm. (magnets are slightly smaller) * Our decals are made to last - Crafted with eco-solvent ink and a durable vinyl medium, these stickers are designed to withstand even the harshest weather conditions, ensuring that they'll look great for years to come. Plus, unlike paper stickers, vinyl material comes off easily and won't tear to shreds. Our high-quality bumper stickers and car magnets are built for the long haul. * It's not going anywhere - Our stickers are incredibly tacky 😜, and our magnets stay on the metal surface where they're placed, thanks to their strong adhesive or magnetic rubber.
