This elegant brass gourd-shaped cap serves as a functional and decorative component for perfume atomizers or essential oil diffusers. Crafted from polished brass with a warm golden finish, it features a traditional double-gourd (hulu) silhouette—symbolizing prosperity and longevity in East Asian culture—measuring 15mm in height and diameter, with a precise 3.5mm inner bore for secure attachment to standard glass or metal spray nozzles. The smooth, seamless casting ensures durability and a refined tactile experience, while the flat base provides stability when placed upright. Ideal for custom fragrance systems, luxury refillable perfume bottles, or artisanal aromatherapy setups, this cap blends heritage-inspired design with modern utility. Its minimalist aesthetic complements both contemporary and vintage-style containers, making it a versatile accessory for personal care, home fragrance, or gift packaging. Not a wearable item but a high-quality hardware component designed for precision fit and long-term use.
