TouchAppear / Bus Handrail


During the COVID epidemic prevention period, the handrails on the public transportation became the medium of virus transmission. If the temperature-sensitive clay is used, people can detect the traces of previous users as the shape and color changes . We help this would raise the awareness of epidemic prevention.
With a long-lasting grip, the temperature-sensitive material will change from orange to red ( or from red to white).
