50ml Serum Bottle(JH-189G)

This 50ml flat square cosmetic bottle is a modern and ergonomically optimized packaging solution, specially designed for storing facial essences, plant essential oils and other high-value skincare liquids. Featuring a sleek flat square bottle shape, it abandons the dull traditional cylindrical design, presenting a minimalist, fashionable and high-end visual texture. The scientific bottle body structure fits the hand perfectly, bringing a comfortable grip experience for daily use, liquid extraction and portable carrying. Meanwhile, the stable structure ensures firm placement, greatly enhancing both the ornamental value and practicality of cosmetic packaging.
This bottle adopts a premium matching accessory system with standardized 20-thread specification, featuring stable structure and excellent sealing performance. It is fitted with a high-grade tall PETG middle collar, which boasts high transparency, strong toughness and outstanding durability, with no deformation or aging after long-term use. Paired with a soft and high-elastic silicone rubber cap, the accessory set achieves excellent airtight and leakproof effects. Equipped with a standard 20# PE guide plug and a 7mm round-head low-borosilicate glass tube, the whole assembly is professionally structured to adapt to various skincare liquid ingredients.
All accessories are made of safe, non-toxic and chemically stable materials, which will not react with essence and essential oil components, effectively isolating external air and dust. This greatly prevents liquid volatilization, oxidation and deterioration, and permanently locks the active ingredients of skincare products. The reasonable dropper structure enables accurate and quantitative liquid taking, effectively avoiding product waste and bringing users a hygienic, convenient and labor-saving using experience.
In terms of personalized customization, this product supports electroplating treatment and special color processing for rubber caps. The minimum order quantity for both electroplated rubber caps and special color rubber caps is 50,000 pieces, meeting the large-batch customization and bulk procurement needs of major beauty brands. Integrating stylish appearance, safe materials and powerful practicality, this 50ml flat square bottle is a reliable and high-cost-performance packaging choice for commercial skincare packaging.
