The brand

A short line with a long shelf life

Hongo Killer is an antifungal brand sold in the United States under a trademark registered in 1993. The registration covers one kind of goods, treatment for the athlete's foot, and it translates the word hongo as fungus.

The line has grown around that one purpose. A powder, a spray powder, two liquid sprays, a cream in two sizes and a brush-on solution all carry a Drug Facts panel. One more bottle, Nail Formula, is sold as a cosmetic.

The packs are bilingual, English and Spanish, and they are easy to spot: lime and yellow cartons, a red band that reads Antifungal, a photo of toes on most fronts.
