3.4oz/100ml PET Rounded Bottom Cosmetic Bottle with 18mm Neck & Flush Overcap

What this packaging is

A rounded bottom silhouette and low-profile flush overcap give this 3.4 oz / 100 ml PET bottle a clean, finished look straight out of the box. The 18mm neck works with a range of closure styles, making it easy to adapt across face cleansers, toners, and light serums. At 4.87 inches tall with a 1.57-inch diameter, the proportions sit comfortably in-hand and read as intentional on shelf. Silk screen printing and heat stamping are both supported, so brand teams can customize without adding a secondary vendor. A solid choice for personal care brands building a cohesive facial care lineup.

Why brands choose this

• Flush overcap creates instant shelf polish: The included flush overcap delivers a seamless, capped profile that looks finished without any extra decoration — a small detail that reads as premium at retail and removes a sourcing step for brand teams.
• 18mm neck opens up closure flexibility: Compatibility with a range of 18mm closures means brands can swap in pumps, disc tops, or flip caps without retooling the bottle, making it easy to range across multiple SKUs or pivot during development.
• Proportions built for the facial care ritual: At 3.4 oz and a slim 1.57-inch diameter, this bottle fits naturally into a morning and evening skincare routine — the right size for a full-size face cleanser or toner, and easy to grip at the basin.
