☘️ Playful Design, Perfectly St. Patrick’s Day
The artwork says it all: a cheeky frog wearing a cowboy hat, holding a mug with a shamrock. Combined with the witty slogan “If I Shenan Once I’ll Shenanigan”, the design embodies everything we love about St. Patrick’s Day — fun, friendship, and a dash of silliness.

The phrase “If I shenan once, I’ll shenanigan” is a clever twist on the word shenanigans — often used to describe mischief, fun, and playful antics.
