How to store a 5ml perfume decant
For a 5ml decant, preserve the exact source label and follow the seller's container guidance as well as sensible cool, shaded storage. A transferred container should not be treated as the original manufacturer's package.
A HUME Fragrance buying guide

Keep source information
Record claimed maker, version and who supplied the decant. Do not identify it only by a shortened nickname.
Check closure instructions
Caps and refill mechanisms differ. Avoid forcing seals or opening parts without guidance.
Separate storage and authenticity
Good care cannot establish where the liquid came from. Keep sourcing claims and handling observations distinct.
Try this before you buy
Save the decant's source identity and container instructions before placing it with similar vials.
