Indians Decals & Stickers - Page 2 Our decals are made of high-quality, weather-resistant vinyl with an average outdoor lifespan of 5–7 years. They are constructed from 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 areas shown in the preview represent the vinyl in the color of your choice. The decals are easy to apply, and detailed installation instructions are included with every order.
