I think we can safely say that plastic on mobile phones is absolutely last year. Kaso is a concept phone created by Junguk Shin designed to celebrate metal as the future of mobile technology. The phone however debunks the futuristic look and opts for a more Vertu-esque style with its blend of rich gold and satin black. This style, crafted for the upper echelon with its gold accents and crisp edges, breathes life into a dying category of drool-worthy luxury smartphones. Designer: Junguk Shin
