Omi International is one of the main brands responsible for importing poor quality "tourist" Ukuleles into Hawaii and this is big part in this business, however they also use the brand name Leolani for supposedly better than budget quality Ukuleles that are at least partly assembled in Hawaii to justify the "made in Hawaii" tag. 

The Leolani range covers all the scales from Mini to Baritone in a variety of, usually laminate, woods and I have seen Pineapples, Lili'us and Taropatches too. In 2012 they started with a new branding of the Waikiki Ukulele Company, (makes for a crowded headstock logo), and I have seen Sopranos Concerts and Tenors carrying this branding. They may well own other brand names too but it is difficult to work out what they own, what they just distribute, and what they have received from their, (I believe its Rockson Music) manufacturing supplier and not rebranded?
