1. Convenient application: Plastic ball bottles with essential oils are easy to use and allow for quick and mess-free application of the oil onto the skin or the affected area.

2. Portable: Plastic ball bottles are lightweight and compact, making them easy to carry around in a purse or pocket for on-the-go use.

3. Controlled dosage: The ball applicator on the bottle allows for controlled dispensing of the essential oil, ensuring that you get the right amount each time without wastage.

4. Long-lasting fragrance: Essential oils are highly concentrated and a little goes a long way. By using a plastic ball bottle, you can ensure that the scent of the oil lasts longer on the skin or in the air.

5. Safe storage: Plastic ball bottles are airtight and can help protect the essential oil from light and air exposure, which can degrade the quality of the oil. This helps to preserve the potency and effectiveness of the oil for a longer period of time.

Overall, using essential oils in plastic ball bottles is a convenient and effective way to enjoy the benefits of aromatherapy and natural healing on the go.
