30ml Serum Bottle（JH-24G）

This 30ml cosmetic bottle features a sleek and slender rectangular bottle shape with a moderate capacity, achieving a perfect balance of aesthetic presentation and practical application. The streamlined slender structure delivers a neat, high-end visual effect, which is different from conventional round bottles, bringing a unique and premium product texture. With moderate volume design, it is neither too bulky for daily storage nor too small for frequent use, making it highly versatile for diversified cosmetic packaging scenarios. This bottle is specially suitable for packaging skincare essences, hair care essential oils and other high-value liquid products, meeting the daily use and commercial sales needs of beauty and hair care brands.
This 30ml slender rectangular bottle is fitted with a high-quality PETG dropper assembly, adopting safe and durable cosmetic-grade materials to support long-term storage and daily use of beauty liquids. The complete accessory configuration includes a PETG middle bundle, silicone rubber cap, 7mm round-head glass tube and 20# PE guide stopper. Known for high transparency, excellent toughness and chemical stability, the PETG middle bundle resists corrosion from essence and essential oil ingredients, avoiding deformation, discoloration or cracking during long-term use. The flexible silicone rubber cap features superior sealing performance, soft texture and aging resistance, which is safer and more adaptable to cosmetic packaging than ordinary rubber materials.
Matched with a premium 7mm low-borosilicate round-head glass tube, the dropper system boasts stable chemical inertness, which will not react with skincare and hair care ingredients, effectively protecting the activity and purity of internal liquids. Cooperating with the 20# PE guide stopper, it achieves uniform liquid output and accurate dosage control, while forming a tight internal sealing structure to prevent liquid leakage, volatilization and air infiltration, greatly extending the product shelf life. In terms of customized production specifications, this product has a fixed minimum order quantity standard. The MOQ for both conventional electroplated rubber caps and custom special-color rubber caps is 50,000 pieces. Featuring a stylish slender rectangular shape, reliable material performance and wide applicability, this 30ml bottle is a professional and cost-effective packaging option for skincare essences and hair care essential oils.
