The Treasure Mug takes its name from an illusion it creates, appearing as if it’s a treasure chest emerging from sand. The trick is pretty simple: a slanted base and trimmed handle creates, what I think, looks more like a mug sinking into a table. Either way, it’s sure to make your morning coffee a bit more interesting!
(PS: I love the very serious Japanese disclaimer: “Please note that when placed on surface, this cup will be slanted. This design is intentional and is not a defect.”)
