Plast: K1: K1 Glow: A durable plastic similar to K1 Line but with a glow-in-the-dark feature. Kastaplast Glow runs apply a phosphorescent additive to the brand's K1 premium chemistry so the disc charges under sunlight or a UV torch and glows visibly during dusk and night rounds. K1 Glow is Kastaplast's standing catalog entry for the format; broader Glow releases on other plastics surface as event runs. The glow pigment is mixed throughout the plastic rather than coated on the surface, so the effect survives the same chips and beat-in that the underlying base plastic absorbs. Flight characteristics match the underlying plastic; the glow chemistry adds visibility without changing how the mold flies.
