Thanks for being a returning customer, Hazel. It's common to experience olfactory fatigue where we become less sensitive to a familiar scent over time (like perfume!). With Himalayan Tea being a more subtle fragrance, this effect can be more noticeable. You can flip the reed sticks for a strong burst of scent. Alternatively, do consider switching up the scent every month with our Coral Diffuser that comes with a pack of different hotel/signature essential oils. Or use a room spray for fragrance whenever you need it. Hope this helps! :) - Julia from Pristine.
