Under the pandemic, more and more people are shopping online than going to stores. They may meet the difficulty of choosing the best size product they want. When customers shop in stores, they don’t have to carefully read the volume since their eyes provide visual image feedback to help make a choice.

My service can fulfill customers' needs. They can choose a reference object for products to compare the size in visual. The object not only comes from their shopping history on that website or APP, but it can also from the service database.
