Storage guides
How to store cologne
Store cologne as directed for the exact product, closed and protected from unsuitable heat and direct light. Identify whether you own a splash, atomizer or another presentation before deciding how the closure should be handled.
A HUME Fragrance buying guide

Read the full product identity
The word cologne can be used broadly. Keep the actual label so you know the maker's format and storage information rather than relying on the category alone.
Use the designed closure
A splash cap and spray assembly are not interchangeable. Close the bottle as supplied and avoid forcing parts open for a transfer.
Keep it away from display hazards
A bright shelf or hot vehicle is not justified by a fresh scent style. Choose an appropriate stable location following the product's guidance.
Try this before you buy
Identify the bottle presentation and check its storage location before treating it as an everyday carry product.
