This cosmetic bottle is equipped with a high-grade 20-thread tall PETG middle collar assembly with upgraded material configuration for superior texture and durability. Both the tall middle collar and threaded cap are made of premium PETG material, which features high light transmittance, excellent toughness, scratch resistance and anti-aging performance.

Equipped with a 7mm round-head low-borosilicate glass tube, the dropper has stable chemical inertia, which will not produce chemical reactions with various cosmetic ingredients, ensuring safe, clean and hygienic liquid extraction every time.
The overall optimized accessory structure realizes stable and quantitative liquid taking, effectively avoiding waste of high-cost skincare raw materials and bringing users a precise, labor-saving and comfortable use experience. Adhering to exquisite craftsmanship and safe material selection, this 30ml straight round glass bottle combines classic appearance and practical functions.
