Choosing sample formats
How to choose fragrance sample packs
Choose a fragrance sample pack by relevant variety, clear quantities and how much control you want over the contents. A large pack can be less useful if many included directions are ones you dislike.
A HUME Fragrance buying guide

Compare the assortment
Read exact identities rather than only broad collection names. Count the choices that address your interests.
Choose selection control
A fixed assortment can invite surprise; a selectable pack can avoid known dislikes. Neither method is automatically better.
Assess manageable quantity
Plan separate trials and repeat favorites. More samples are not useful if you will not work through them.
Try this before you buy
Count relevant scent questions in each pack rather than simply counting vials.
