Sony Corp. has expanded its marketing channels and taken new approaches to promoting a portable aroma diffuser launched about a year ago dubbed the "aromatic Walkman."
Nicknamed after its iconic audio product, Sony released the Aromastic in October last year with a special structure that allows people to carry their favorite scents wherever they go and savor their aromas in a way that does not offend people nearby.
The personal portable diffuser looks like a large lipstick. Cartridges for five different scents are inserted so people can refresh themselves with the scent of their choice.
