How to store roll on perfume
Store roll-on perfume with its cap securely closed and according to the formula's actual directions. The roller describes an applicator, so it does not establish carrier, shelf life or one universal storage specification.
A HUME Fragrance buying guide

Keep the label visible
Retain the full name and formulation claims. A similar roller bottle may contain a different cosmetic product with different intended use.
Protect the contact mechanism
Handle the applicator as directed and avoid unnecessary contact with its parts. Do not remove the roller assembly unless the maker specifically instructs it.
Choose storage before carrying
Review temperature and light guidance and keep the closure secure in a suitable place. Portability is not a guarantee against leaks or unsuitable exposure.
Try this before you buy
Record the carrier information and check the closure separately before choosing where a roller bottle will stay.
