30ml Serum Bottle（JH-201X）

This 15ml and 20ml square cosmetic bottle features a straightforward vertical square structure with neat and smooth body lines, presenting a minimalist and sophisticated visual style. The solid square base ensures stable placement on any flat surface, effectively avoiding shaking and tipping during daily use and display. With two practical capacity options, this container flexibly adapts to diversified application scenarios, including commercial formal packaging, daily household skincare and portable travel use. It is specially developed for liquid beauty formulations, serving as an excellent packaging container for facial essences, plant essential oils and other concentrated skincare liquids, fully matching the lightweight and high-quality positioning of modern cosmetic products.
The bottle is fitted with a standard 20-tooth full-plastic press dropper with complete professional accessories and high-quality material collocation. The middle collar and press button are both made of high-strength ABS material, which delivers outstanding hardness, wear resistance and structural stability. It can withstand frequent repeated pressing without deformation, loosening or damage, ensuring long-term stable use. Equipped with a safe PP inner lining, the bottle mouth achieves a tighter and healthier sealing state with excellent chemical inertness, which will not react with skincare ingredients and can well protect the internal liquid purity.
Matched with a durable NBR rubber cap, the dropper forms an efficient airtight barrier that effectively isolates external air, dust and moisture, preventing essence and essential oil from oxidation, volatilization and deterioration to lock product activity. Supported by a 7mm low-borosilicate round-head glass tube, it realizes smooth, uniform and quantitative liquid extraction, allowing users to accurately control skincare dosage and reduce unnecessary product waste. Combining simple three-dimensional square aesthetics, safe full-plastic accessories, reliable sealing performance and user-friendly operation, this bottle perfectly integrates beauty and practicality, being a cost-effective and ideal packaging solution for mid-to-high-end essence and essential oil cosmetic products.
