T-Shirt Tシャツ

This design features a humorous and relatable cartoon of an visibly exhausted brown owl. The bird has heavy, drooping eyelids and a weary expression, with a black "Z" floating above its head to emphasize its sleepiness. It is standing and clutching a white ceramic mug tightly with both wings. The mug displays the text "NIGHT SHIFT FUEL" in bold blue letters, accompanied by a small icon of a steaming cup of coffee, set against a clean, light gray background.
