50ML square rounded corner bottle（JH-49Y）

② This 30ml bottle, featuring a sleek square design with rounded corners, is an ideal container for serums, essential oils, and similar products. Its minimalist shape combines practicality with aesthetic appeal—the square structure optimizes storage efficiency, while the rounded edges enhance safety and add a refined touch, making it both user-friendly and visually pleasing.

Complementing the bottle is a high-quality electrolytic aluminum dropper, meticulously constructed with multiple components to ensure functionality and safety. The dropper includes a PP (polypropylene) inner lining, which meets cosmetic-grade standards to prevent any chemical interaction with the contained products. Its outer shell is made of aluminum oxide, providing durability and a premium metallic finish. The 20-thread trapezoidal NBR (nitrile butadiene rubber) cap ensures an airtight seal, effectively preventing liquid volatilization and contamination, thus preserving the product’s efficacy.

Additionally, a 20# guide stopper made of PE (polyethylene) is included. This stopper facilitates smooth insertion and removal of the dropper, ensuring a seamless user experience, while also reinforcing the seal to maintain product freshness during storage and use.

With its well-designed capacity, durable materials, and thoughtful component integration, this bottle offers a reliable and attractive packaging solution for premium serums, essential oils, and other liquid skincare or aromatherapy products.
