Turpen is a high-fantasy, realistic potion bottle crafted from thick, dark green glass with a slightly irregular, hand-blown shape. The bottle features a rounded base that tapers into a narrow neck, sealed with a wax-dipped cork. Its surface is smooth with subtle imperfections, giving it an authentic, artisanal look. The glass has a faint luminescence, suggesting magical properties, and is adorned with delicate, gold-leaf runes that circle the neck, hinting at its alchemical significance.
