Each scent is a street in the month it belongs to: the flower market on Hàng Lược the week before Tết, the lotus beds on West Lake at dusk, Nguyễn Du at night when the milk flowers open, the riverbank under Long Biên bridge in December. Scroll and you walk down the street until it peels away and the next season is standing behind it. Click the bottle in any season to read its notes. At the end, sliders let you mix your own blend, and every mix gets its own name.
