How long does one brick last?

Longevity depends on cabin size, ventilation, and how often you drive. The solid brick design releases fragrance gradually—you'll get weeks of noticeable scent under normal use.

Will this stain or damage my dashboard or upholstery?

The solid brick format won't leak or transfer oils. If you place it on the dash or console, make sure the surface is clean and dry first. No adhesive needed—just set it down or hang it.

Can I use this in a truck cab or larger vehicle?

Yes. A single 200g brick works well in sedans and compact trucks. Larger cabins or SUVs may benefit from a second brick if you want stronger fragrance saturation.
