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.
Our new plastic K2 is similar to K1, but more flexy and grippy. Just as with K1, our new plastic will come in both translucent and solid colors.
K3 is our base line plastic – grippy in all conditions. With this plastic you will get that nice worked in feel pretty quickly. Compared to other base plastics, K3 is medium soft.
