Welm customization is not just about cups, but also an interactive carrier: it can be designed with a tear off surprise area (hiding coupons, QR codes, fun Q&A), a temperature sensitive color changing pattern (showing brand slogan when exposed to heat), and a DIY graffiti area (encouraging users to create and share again), allowing consumers to actively take photos and broadcast, unlocking new gameplay of "social fission".
