The 4.06oz/120ml 20-400 Round PETG Serum Bottle with Metallic Red PP Lotion Pump from Guangzhou Keyuan Plasticware Co., Ltd. is the largest bottle in the tapered PETG serum series. Its gently curved round profile, crafted from clear PETG, delivers a refined aesthetic that lends itself well to premium serum and essence packaging. PETG's glass-like surface clarity keeps the packaging looking high-end without the weight or fragility of glass, and the metallic red spray-coated lotion pump adds a strong visual signature for brand differentiation. The 20-400 neck finish is compatible with the included pump and other standard closures. At 169mm total height with pump, the bottle features a 95mm printable decoration area — the largest in this tapered PETG series — providing ample room for label design, ingredient panels, and branding elements. Suitable for face serums, essences, toners, and anti-aging skincare treatments. Custom colors are available. Request a quote or sample from Guangzhou Keyuan Plasticware Co., Ltd. to learn more.
