KobraCast is the most versatile Worbla. One of the many features of KobraCast is that you can sew through it quite easily for attaching leather, fur, fabrics and more. As KobraCast is exceptionally lightweight, it is ideal for a stabilizing substructure to use for bags, corsets and much more! This Worbla is a lightweight, mesh-reinforced thermoplastic designed for forms that need flexibility, strength, and stability all at once. It’s also a fantastic choice when you want durable structure without the weight.
