20ml Serum Bottle（JH-202G）
This versatile cosmetic bottle is available in 15ml and 20ml practical capacities, adopting a sleek and minimalist square structure with a solid square base. The bottle features a straight vertical body with clean and neat lines, creating a sophisticated, modern and understated aesthetic that fits perfectly with high-end cosmetic branding. Its square bottom design ensures stable standing on display racks, dressing tables and travel kits, effectively preventing sliding and tipping. With dual optional capacities, it caters to multiple usage scenarios, including official product packaging, daily household skincare and portable outdoor use. Specially engineered for liquid beauty products, this bottle is perfectly suitable for storing facial essences, pure plant essential oils and various concentrated skincare liquids.
The bottle is equipped with a standard 20-tooth dropper set with upgraded premium material configurations. Different from ordinary plastic accessories, the middle collar is made of high-quality PETG material, which boasts high transparency, excellent toughness, impact resistance and superior chemical stability. This premium material resists corrosion from various skincare ingredients, avoids yellowing and deformation during long-term use, and maintains a flawless appearance. Cooperating with a durable NBR rubber cap, the dropper forms a highly airtight sealing system. It effectively isolates outside air, dust and humidity, preventing the internal essence and essential oil from oxidation, volatilization and deterioration to retain product activity.
Fitted with a 7mm low-borosilicate round glass tube, the dropper features high light transmittance, smooth liquid delivery and stable chemical inertness, ensuring safe and clean liquid extraction every time. The precise 20-tooth specification enables tight and firm fitting between accessories for stable daily use. The dropper design allows users to take liquids quantitatively and accurately, greatly reducing product waste and improving utilization rate. Integrating fashionable square styling, high-grade PETG accessories, reliable sealing performance and safe material properties, this 15ml-20ml square bottle perfectly combines aesthetics and functionality, standing as an ideal professional packaging container for essence and essential oil cosmetic products.
