Tour Series Joseph Anderson K1 Hard (7)

The Järn by Kastaplast fills a special role in your bag—designed to execute when the pressure is on. With flight numbers Speed 4.5, Glide 3.0, Turn 0.0, and Fade 3.0, this midrange offers a flight pattern suited for intermediate and advanced players. Not afraid of wind, this disc wraps up its flight with dependable stability. You’ll love it off the tee—or as a reliable option for second shots.

Plast: K1 Hard: K1 Hard Line: Very similar to K1 plastic but significantly stiffer. Kastaplast Tour Series is the top-tier branded-athlete release, typically priced 20–60% above the standard version of the same plastic and produced in tightly limited quantities. Each Tour Series run features a signature hot stamp tied to a specific Kastaplast pro plus a premium cosmetic — custom dyes, layered foil, or specialty rim work — that distinguishes it from the regular catalog version. The underlying plastic is most often K1 or K1 Glow, so flight numbers and durability match the base premium chemistry; the price premium pays for the artwork, the limited supply, and a contribution to the athlete. Tour Series discs are popular with collectors and with players who want to throw the same exact plastic chemistry as the pro while carrying a distinctive stamp. Because the plastic is unchanged, the disc breaks in and seasons exactly like a standard K1 or K1 Glow run of the same mold — the stamp and colorway have no effect on how it wears in or gains turn over time. On the second-hand market unthrown Tour Series copies tend to hold value well thanks to the limited release and strong demand for Kastaplast, while a played example seasons and resells along the same curve as the base plastic underneath.
