T-Shirt Tシャツ

An adorable cartoon illustration featuring a fluffy brown owl fast asleep tucked inside a white coffee mug. This sleepy bird is resting its head on the rim of the cup with "Zzz" symbols floating above, perfectly capturing the struggle of waking up. The mug displays a prominent red label with the text "TOO TIRED," humorously symbolizing exhaustion, caffeine cravings, and Monday morning moods. The design utilizes clean lines and soft colors in a kawaii vector style.
