Buying Guide
What to consider when selecting 120 ml plastic bottles:
- Material and safety: Choose LDPE for flexibility and good chemical resistance, or other food-grade plastics if you require a higher standard of purity for consumables.

- Mouth size and mouth design: Wide mouths ease filling and cleaning; narrow mouths reduce spills during pouring.
- Dispensing method: Droppers, squeezable tips, or simple caps suit different liquids like oils, cosmetic serums, or paints.
- Reuse and sterilization: Reusable containers should withstand regular cleaning or sterilization to support eco-friendly use.
- Compatibility: If you use a diffuser or a specific device, verify fit and compatibility with the bottle size and cap type.
- Labeling and organization: Includes label sheets or clear labeling areas to help you categorize contents and track refills.
