Alcohol free perfume sample size options
Alcohol-free perfume samples need two separate checks: the exact formulation claim and the actual quantity or applicator supplied. A small oil-like bottle or roller is not proof that a sample meets your alcohol requirement.
A HUME Fragrance buying guide

Verify the specific requirement
Ask the maker about the exact item if absence of a particular alcohol matters. A seller's broad category description may not answer that question completely.
Read the presentation
Sprays, balms and contact applicators can have different units and use instructions. Compare like-for-like where possible and do not invent a gram-to-spray conversion.
Keep records of the product
Save the formulation information and exact name with your trial notes. A later similarly named purchase should not be assumed to use the same carrier.
Try this before you buy
Confirm the exact alcohol claim before comparing sample amount, price or application convenience.
