The Svea is a versatile midrange from Kastaplast. It is a beaded, neutral-flying disc that will hold any line it is put on. When thrown with power, it will hold a trustworthy, understable line.
 
Kataplast K1 is a unique plastic blend manufactured in Sweden. This disc plastic has an excellent feel. It is moderately grippy, but not sticky and is extremely durable. K1 plastic has a similar feel to Prodigy 400G or Prodiscus. K1 is a stiffer blend than Kastaplast's K2 plastic.
