Fi (Фи) is a Russian interjection used when coming into contact with something unpleasant, such as insects.
Fi (Фи) is a line of creams and sprays designed to protect against mosquito and midge bites and to relieve their aftereffects. The products soothe itching, irritation, and discomfort, restoring a sense of calm.
The visual identity of the packaging is built around typography: the silhouette of a flying insect is encoded in the Cyrillic letter “Ф” (pronounced “ef”), turning the name into a distinctive symbol.
