20ml Serum Bottle（JH-20Z）

This 20ml cosmetic bottle features a classic slim straight round shape, presenting a simple, neat and sophisticated overall look. The slender body design delivers a minimalist and modern aesthetic, which is both visually appealing and space-saving for storage and display. With a standard 20-caliber specification, the bottle is professionally configured for holding essence, pure essential oil and various concentrated skincare liquids, perfectly matching the packaging demands of mid-to-high-end skincare products. Its compact 20ml capacity achieves an ideal balance between daily household use and portable travel use, avoiding product deterioration caused by long-term storage of large-capacity containers and meeting the lightweight carrying needs of business trips and outdoor activities.
Equipped with a complete set of high-precision 20-tooth needle-type press dropper accessories, this bottle adopts premium graded materials to ensure excellent safety and stability. The dropper’s inner lining is made of food-grade PP material, while the middle collar and press button are crafted from durable ABS material, which offers high hardness, wear resistance and long-lasting structural stability for frequent pressing operations. Fitted with a low-borosilicate round-head glass tube, the dropper features high transparency, corrosion resistance and chemical stability, which will not react with essential oils and essence ingredients to ensure pure product quality. The supporting NBR rubber cap enhances the overall sealing performance, effectively locking in product activity and preventing liquid volatilization, oxidation and leakage.
Additionally, the bottle is matched with a 11.8 PE wiper plug, which can thoroughly scrape residual liquid on the inner wall of the glass tube and the bottle mouth. This practical design greatly reduces product waste and improves the utilization rate of skincare liquids. The integrated press-type structure enables precise and quantitative liquid output, allowing users to control the dosage accurately for each skincare application. Combining exquisite appearance, safe materials and humanized functional design, this 20ml bottle is a versatile and high-quality packaging container for essence and essential oil products in the beauty and cosmetic industry.
