Clear double old-fashioned/mai tai glass deigned by Tiki tOny, with dark blue and black printed artwork featuring a pot still, a barrel, a thatched meeting house with palm trees, and two idols along with a badge stating "Teeling Whiskey since 1782".
Possibly part of a gift set for their small batch whiskey aged in rum barrels. Although designed directly by Tony as a project for Teeling Irish Whiskey (based in Dublin), these were also distributed by Forbidden Island in Alameda in June of 2020 as part of their cocktail shack special which included a pre-batch cocktail and two of these glasses:
"The Teeling Fighting Irish is a delightful grog featuring Teeling Irish Whiskey, guava, lime, honey and spice. We have 32 available in a 22oz serving for four and each bottle comes with two complimentary Teeling Mai Tai glasses designed by Tiki Tony!”
