Nag Champa roll on

I'm not sure why I think the roll on is different than the non roll on bottles. I have been purchasing this product ( tiny bottles ) for years and I love it. In fact, I have saved bottles from other products and poured your product into them (after purifying). I noticed with this order the "tiny" bottles are larger (which means more volume ) but for some reason the scent isn't quite right. I hope it is my smeller and not the product's chemistry.
