It smells like dirty public toilets (urine). Very strong and foul smell, nothing to do with lavender.

After 3 days of leaving the packages outside on the balcony, this smell has somewhat faded.
I read that there is a mixture of chemicals and it is not pure lavender, hence the very strong and strange smell they leave behind.
Now I light them outside on the balcony as the bad odor is very difficult to get rid of indoors.
