The bottle supports two professional press dropper configurations to meet diverse usage needs. The first model is the ZK-D71 press-type dropper, consisting of a press button, ABS middle bundle, PP inner lining, 20-tooth NBR press dropper cap, 7mm low-borosilicate round-head glass tube and upgraded 20# PE guide stopper. Each component is selected with high-standard materials, featuring good chemical stability and tight sealing performance to prevent liquid leakage and ingredient oxidation. The second option is the ZK-D787 rotary press dropper, equipped with an ABS button, 304 stainless steel spring, PETG middle bundle, PP tooth cap, PE piston, nitrile rubber dropper sleeve and glass tube. The 304 steel spring ensures flexible and durable pressing rebound, while PETG and PP accessories deliver excellent corrosion resistance and structural stability.
Both dropper configurations adopt humanized structural design, enabling precise liquid output and accurate dosage control for essential oil and essence use. The NBR and nitrile rubber accessories provide superior sealing and aging resistance, adapting to long-term product storage, while the low-borosilicate glass tube effectively isolates chemical reactions and protects the activity of skincare ingredients. In terms of production customization, the minimum order quantity for both conventional electroplated rubber caps and special-color customized rubber caps is fixed at 50,000 pieces. With sturdy bottle body, diverse functional configurations and reliable quality, this 30ml bottle is an ideal cost-effective packaging solution for mass production and sales of skincare liquid products.
