A medium-sized glass vial with a slightly bulbous base and a narrow neck, sealed with a cork stopper. The potion inside emits a vibrant orange glow, suggesting its magical properties. The glass is smooth and transparent, allowing the luminous liquid to be clearly visible, with subtle imperfections like small bubbles or slight unevenness in the glass thickness to add realism. The label, if present, is aged parchment with elegant, handwritten script detailing its effects, slightly worn at the edges.
