Kastaplast started out as a small disc design workshop in 2011, using front line working tools such as 3D printing, computer flight simulation and wind tunnel tests. Kastaplast is based in Stockholm, Sweden.
K1 plastic 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 plastic (formerly known as K2 plastic) is similar to K1, but more flexy and grippy. Just as with K1, K1 Soft plastic comes in both translucent and solid colors.
K3 plastic is Kastaplast's 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.
K1 Glow plastic is the same super durable plastic as K1, but powered with glow!
Kastaplast Glow is currently out of stock at the factory. We will purchase them as soon as they are available.
