K1 Grind
The sustainable version of Kastaplast's premium K1 plastic. Made from 100% recycled K1 plastic — Kastaplast collects the leftover material from its own K1 disc production, grinds it and turns it into new plastic without mixing it with other materials or using second-hand discs. The result has the same quality, durability and grip as standard K1, but with a significantly lower environmental impact. Some players notice that K1 Grind flies a bit more stable than standard K1.
