A small, flask-shaped vial with a slightly curved body and a narrow neck, designed for easy handling. The glass is thick and tinted a deep blue, with a subtle luminescent glow that pulses faintly, indicating its magical properties. The surface is smooth with a few engraved arcane runes circling the base, adding to its mystical appearance. A cork stopper, wrapped in a thin strip of enchanted leather, seals the potion securely.
