From Luftwerk is the STELVIA XSP (PLASTIC) – The concept summary of this yoyo was to build an “Extreme Stability Plastic” that made this model feel like a metal yoyo, even more so than the Fulvia. This was achieved by using rotational inertia numbers and comparing them directly with 6061 yoyos.
The result is a yoyo that has a closer performance of a metal yoyo even though it is made out of plastic. The branding has been heavily inspired by more Japanese & Scandinavian design elements as a contrast to the intimidating concept of performance. I will be writing an extensive article on the development of this project!
