Softball Decals & Stickers Our decals are made from high-quality, weather-resistant vinyl with an average outdoor lifespan of 5–7 years. This is the same durable material used for semi-trucks and outdoor signage. Please note that 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 will be provided in the color of your choice. Installation is simple, and easy-to-follow instructions are included with every order.
