A medium-sized, flask-shaped potion with a robust glass body, featuring a slightly curved neck and a cork stopper. The glass is thick and slightly opaque, with a deep crimson liquid inside that faintly glows, suggesting its magical properties. The flask is adorned with golden filigree that wraps around the neck and base, adding an ornate touch to its otherwise simple design. The label is aged parchment, tied with a red ribbon, bearing arcane symbols that hint at its rejuvenating powers.
