1oz/30ml 20-400 PET Round Cosmetic Bottle with Oversized Dropper

What this packaging is

A slim 37mm cylinder profile with a 20-400 neck finish, this 30ml PET round bottle pairs with an oversized dropper closure to create a format serum and oil buyers immediately recognize. The 1oz/30ml 20-400 PET Round Cosmetic Bottle with Oversized Dropper suits face serums, face oils, hair oils, essential oils, and CBD oils, delivering a travel-ready, shatter-resistant alternative to glass. The standard 20-400 thread also opens the door to pumps or other closure swaps as your line evolves. Manufactured in China with silk screen and heat stamp decoration support, it gives brands a clean canvas to build a shelf-ready identity.

Why brands choose this

• Dropper format matches the serum ritual: The oversized dropper closure signals precision dosing, which is exactly what consumers expect from a face serum or facial oil. That category-appropriate ritual cue builds instant consumer confidence and drives repeat purchase in a market where ingredient trust is everything.
• 20-400 neck finish keeps your options open: The standard 20-400 thread is compatible with a wide range of closures beyond the dropper, including pumps and disc caps. That interchangeability means brands can reuse the same bottle across different SKUs or reformulate into a pump format without retooling the entire component.
• 30ml size hits the travel and trial sweet spot: At 1oz/30ml, this bottle clears TSA carry-on limits and fits naturally into sample and starter-size product lines. For CBD oils, hair oils, and essential oils, the compact footprint also lowers the cost-per-unit at the shelf, making it easier for buyers to try a new brand.
