there is a SoHa store in Kahala Mall. super popular with local people and super popular with japanese tourists.
they sell all kinds of cool shells and things to make your house feel like you’re at the beach.
the SoHa Diffuser is the best. kind of expensive but lasts for 2 years. coming home with the fresh aroma is cool.
my recommendation is the Moana diffuser oil. it contains gardenia, pikake, lilac, hyacinth, mimosa, flower, and rose. made in hawaii ne! i have one in my room and love the smell when i sleep at night, and wake up on the morning.
