Suggestion : To enjoy the full fragrance throw, you may wish to reorder some new fibre reeds especially if you've been using your existing ones for a while.
This scent is so beautiful and not at all overpowering. I've had bad experiences with home scents in the past (not from Castell apothecary), they tend to give me headaches and make me sneeze. Not this one though, it smells so natural, and a bit spicy, not cloyingly sweet. I'll definitely buy it again when I run out.
