30ml Serum Bottle（JH-247P）

This 30ml square cosmetic bottle is a minimalist and practical packaging container designed for high-quality skincare essences, essential oils and other liquid beauty products. Featuring a neat square structure with a standard square bottom, the bottle presents a simple, crisp and modern visual effect, breaking the conventional round bottle design and bringing a stable, tidy and high-grade packaging texture. The streamlined and uncomplicated bottle body structure not only improves the overall three-dimensional sense and display effect of the product, but also ensures stable placement, convenient storage and easy carrying, perfectly balancing elegant appearance and daily practicality. With a moderate 30ml capacity, it is highly suitable for official sales, customer trial packaging and daily personal use.
This bottle is equipped with a practical 20-tooth full-plastic dropper assembly with reliable and standardized material configurations, ensuring safe storage and accurate liquid taking for skincare liquids. The complete accessory set consists of an NBR rubber cap, PP middle bundle and low-borosilicate glass tube, all adopting cosmetic-grade safe materials that feature stable chemical performance and excellent ingredient compatibility. The PP middle bundle delivers outstanding toughness and corrosion resistance, effectively resisting erosion from essential oil and essence components, while the high-quality NBR rubber cap offers superior elasticity and aging resistance to achieve long-term stable sealing.
Matched with the low-borosilicate glass tube with excellent chemical inertness, the dropper system avoids chemical reactions with internal liquids, fully protecting the activity and purity of skincare ingredients and preventing deterioration and oxidation. The integrated structural design effectively prevents liquid leakage and volatilization, greatly extending the product shelf life. In terms of customized production rules, the product has a unified minimum order quantity standard. The MOQ for conventional electroplated rubber caps and customized special-color rubber caps is both 50,000 pieces. With concise square modeling, stable accessory performance and wide applicability, this 30ml bottle is a cost-effective and versatile packaging solution for mainstream essence and essential oil products.
