Worbla’s Kobra Cast Art


Worbla’s® Kobra Cast Art (WKA) – the transparent thermoplastic sheet by Cast4Art!

This material is incredibly flexible while it holds its shape very good at the same time. In addition like all the other products of the Worbla’s® Art Series it is non-toxic and solvent-free. The material should be heated to 80-90 °C (175-195 °F).

So it is strongly advised wearing working gloves with rubberized fingers while working with it!
