Kastaplast Järn (K1 Glow)
The Kastaplast Järn in K1 Glow plastic combines the mold’s dependable overstability with Kastaplast’s famously bright, long-lasting glow blend. K1 Glow has a firm, tacky premium feel and typically adds a touch of extra stability, giving the Järn even more confidence in the wind and on high-torque throws—without sacrificing grip or consistency.
Flight Numbers: 4.5 | 3 | 0 | 3
In K1 Glow, the Järn flies stout and trustworthy. It resists turn completely, even when thrown hard, and finishes with a strong, forward-driving fade that you can count on. The added stability from the glow blend makes this version especially effective in headwinds and on forehand approaches where torque resistance matters. Glide stays controlled, keeping approaches from sailing long and helping the disc land where you intend.
