About Bluelet
Bluelet is a cleaner and freshener for flush toilets that Kobayashi Pharmaceutical launched in 1969, anticipating the spread of flush toilets when only about 20 per cent of Japanese toilets flushed. It took the company into household products, a liquid version followed in 2001, and Bluelet Decoral and Stampy were developed from 2014 for tankless toilets. Annual sales exceed 10 billion yen, the company says.
