40ml Serum Bottle（JH-33A）

This 40ml premium glass bottle is a versatile and functional packaging solution specially designed for skincare essentials such as serums, essences, and pure essential oils, perfectly meeting the storage and dispensing needs of high-end liquid skincare products. Adopting a scientific and practical structural design, the bottle is equipped with a complete set of high-quality accessories, including a press-type dropper with middle collar and push-button AB structure, an NBR rubber cap, a PE guide plug, and a 7mm round-head low-borosilicate glass tube, forming a stable, safe and user-friendly overall configuration.
The 7mm round-head glass tube is made of low-borosilicate glass material, which features high transparency, stable chemical properties, and low expansion coefficient. It effectively avoids chemical reactions with essential oils, essences and other active skincare ingredients, ensuring the purity and activity of internal contents. The matched PE guide plug boasts excellent flexibility and fitting performance, which can precisely fix the glass tube, prevent shaking and leakage during use and transportation, and achieve smooth and uniform liquid guiding effect.
The core press-type dropper adopts AB button structure and is matched with a durable NBR rubber cap and standard middle collar. The NBR rubber cap has outstanding oil resistance, aging resistance and sealing performance, which can tightly seal the bottle mouth, isolate air and dust, and prevent volatile skincare ingredients from deterioration and oxidation. The press button design enables quantitative, labor-saving and precise liquid dripping, effectively controlling the dosage of essences and essential oils, avoiding waste and improving the use experience.
With a moderate 40ml capacity, this bottle is compact, portable and easy to store, suitable for daily household use and travel carrying. Integrating safe materials, precise structure and convenient operation, it is an ideal packaging container for mainstream skincare liquid products, supporting daily use, commercial packaging and customized packaging of beauty and personal care products.
