In this video, we take a close look at the Electroplated Airless Bottle in 10/15/20/30ml sizes, showing how the PP pump, AS cap, and PE piston work together to protect serums and essences from air oxidation. You'll see the vacuum structure in action, observe fixed-dosage dispensing, and learn how the high-transparency body helps check remaining liquid. We also demonstrate custom logo and printing options for branding.
