Kastaplast has stated that these glow a little less than previous years.
The Kastaplast K1 Stal Glow is an overstable fairway driver and is named for it’s toughness. Stal, the Swedish name for steel, was once a common solidier’s name. This tradition was started in the sixteenth century when the Swedish military named their soldiers. Stalmannen is the Swedish name for Superman! So with steel built right into it’s name, you can see that the Stal is one tough disc golf driver!

K1 Line is Kastaplast’s super durable material that has a nice combination of firmness and gumminess. Disc golf discs in the K1 Line have both solid and translucent colors.
K1 Glow Line is the same super durable plastic as K1, but powered with glow!
