Horoscope & Zodiac Decals & Stickers - Page 4 This decal is made of high-quality, weather-resistant vinyl with an average outdoor lifespan of 5–7 years. It is the same durable material used for semi-trucks and outdoor signage. These are professional die-cut vinyl decals, not inkjet-printed stickers with white or clear backgrounds. The black area shown in the design represents the vinyl, which is available in the color of your choice. The decals are easy to apply, and detailed installation instructions are included with your order.
