Pink Panther Inside Crystal Pen

A side close-up of a delicate, gorgeous, fully transparent crystal fountain pen. Inside the transparent pen barrel and cap, a pink panther character is carefully placed. This pink panther wears a miniature artist cover-up and beret stained with ink, holding a miniature paintbrush in its paw. It actively and diligently applies blue ink to the pen's internal mechanical mechanism and the inner surface of the nib, as if carefully replenishing the ink flow. The fountain pen floats against a pure light gray background, while the soft directional studio lighting highlights crystalline transparency and vivid blue ink.
