The Kastaplast Berg is a unique putt and approach disc with a curved indented flight plate. This thumb track allows the disc to rest comfortably in your hand and fly with increased consistency. The Berg is a slow flying putter that stays stable and never drifts too far away from the target. 

Katapalst K1 is a unique plastic blend manufactured in Sweden. This disc plastic has an excellent feel. It is moderatley grippy, but not cticky and is extremely durable. K1 plastic has a similar feel to Prodigy 400G or prodiscus. K1 is a stiffer blend than Kastaplasts K2 plastic.

Kastaplast Glow Collection is known for being one of the market's best luminescent discs, both when it comes to shining brightly and shining for a long time. In general, the K1 Glow plastic itself tends to affect the flight characteristics of the disc, so it becomes somewhat more in the overstable direction than the usual K1 plastic
