K1

K1 Line
K1 line is Kastaplast’s super durable material with a nice combination of firmness and gumminess. Discs in K1 Line will appear in both solid and translucent colors.

K1 Soft
K1 Soft is similar to K1, but flexier and grippier. Just as with K1, this plastic comes in both translucent and solid colors. (K1 Soft is the same as the old K2).

K1 Hard
The K1 hard plastic has the same polished and gummy feel as the K1, but it’s slightly harder and doesn’t beat in as fast, it also gives the disc a touch more stability. K1 hard is a tour series disc exclusive.

K1 Glow-Line
K1 Glow has the same properties as the durable K1 Line but is powered with a long lasting glow!
