Planning fragrance quantity
How long will a perfume oil roller last
An oil roller's time in use depends on stated volume, applicator and wearing habits. Oil format does not supply an automatic wear duration, unlimited shelf life or universal skin compatibility.
A HUME Fragrance buying guide

Read the actual product
Confirm ready-to-use perfume and its directions rather than treating every scented oil as the same format.
Track your pattern
Direct-contact application does not translate into spray counts. Use ordinary usage records instead.
Follow care and date guidance
Keep the cap secured and consult maker information about condition or storage rather than guessing from the oil base.
Try this before you buy
Record volume, application method and real frequency before estimating an oil roller's useful quantity.
