卷 juǎn is a brand of on-the-go popiah created to inform the target audience, which are the working adults, the origin of popiah as well as the original way of eating popiah in the past. The popiah wrapper is designed to resemble a old historical chinese text to represent the origin where the magistrate Cai Fu Yi had to copy Chinese historical records. 

There is also a loyalty card where customers have to buy 9 popiah within 49 days to get a key chain. This represents the quantitative research on how Cai Fu Yi had to copy 9 historical records within 49 days, making the loyalty card a form of storytelling of the popiah origin.
