History / About
The plastic counterpart to the Stelvia XP589 titanium, developed simultaneously as a head-to-head material comparison in nearly identical geometry. Nearly the same diameter, width, and shape as the titanium version, yet completely different in character — lighter, more forgiving, and with a softer feel in hand. The project was one of Luftverk’s most deliberate experiments in how material choice transforms play experience within the same design.
