This is a mug shaped like an angry Tiki head with a furrowed brow and an upturned bottom lip. Uniform green glaze.
Originally, this was a one-off design by Bai Tiki which she created in 2009. However, the design was reproduced (poorly) without authorization and BarConic began selling it around 2015-2016.
This is not the only design of hers they have stolen. They also reproduced her 2015 Tiki Pop Fever mug under a new title and without authorization.
As a wholesaler, BarConic buys inventory for low prices from overseas where the copyright laws are not enforced. This mug is one of several designs BarConic has distributed and which do not reimburse the original artists and manufacturer.
