30ml Serum Bottle（JH-203G）
This 30ml square cosmetic bottle adopts a minimalist and trendy square shape, abandoning the conventional single round bottle design. The neat three-dimensional bottle body presents a modern and high-end texture, which is highly compatible with the aesthetic design of mid-to-high-end skincare brands and suitable for product display, daily storage and commercial sales packaging. Featuring a moderate 30ml capacity, this container balances practicality and portability perfectly, ideal for long-term daily use of skincare products. It is widely applicable to hold skincare essences, plant essential oils and various concentrated liquid cosmetics, meeting the formal packaging needs of mainstream beauty skincare products.
The bottle is professionally matched with a high-performance 20-tooth PETG dropper assembly with reliable and high-quality accessories. The dropper’s middle collar is made of premium PETG material, which features excellent transparency, toughness, impact resistance and chemical stability. It is free from deformation and discoloration during long-term use and will not chemically react with internal skincare ingredients. Equipped with a trapezoidal NBR rubber cap, the dropper achieves tight mouth sealing, effectively isolating external air, dust and moisture to prevent liquid oxidation, volatilization and leakage, and fully lock the activity of essence and essential oil.
Supported by a 7mm low-borosilicate round-head glass tube, the dropper ensures smooth, clean and quantitative liquid extraction, allowing users to accurately control the dosage and avoid unnecessary product waste. In terms of customized production, the minimum order quantity for conventional electroplated rubber caps and special-color rubber caps of this product is both 50,000 pieces, suitable for brand batch customization and mass production. Integrating fashionable square appearance, safe and stable material properties and humanized functional design, this 30ml bottle perfectly combines aesthetics and practicality, being a premium and reliable packaging solution for essence and essential oil cosmetic products.
