Sapindus Soap Cup Design / Cup

Sapindus Soap Cup Design

Soapberry is a deciduous tree native to East, Southeast and South Asia. The rind of the fruit contains saponin, which can be used as a natural cleaning soap. In Europe, there are a lot of people like to have the original rind of the fruit without processing packed in the cotton bag soaking in water and rubbed to foam, then directly used to wash clothes, hair and body. The innovation point of this design is to settle a pure natural sapindus soap under the drinking cup. Simply touch the soap at the bottom of the cup, and combine it with the dew on the body of the chilled beverage with the hands and to remove grease stains easily.
