I'd been toying with the idea of making my own perfume for a while and when these arrived, while the time was right to get going! Roller ball bottles are the best way to apply perfumes made with essential oil, if you're making alcohol based perfume, you're going to want to use a spray bottle instead.

Upon doing a little research to make my perfume, I learned something pretty interesting. Bottle to store oils and perfumes should always be dark colored to help prevent spoiling by light pollution. I had thought the dark blue to be a pretty aesthetic choice, but turns out it has a use as well! The gold caps go lovely with the blue color. The bottle are a thick, durable glass and all the caps were un-flawed. I did find them a little stiff to turn, but not to the degree that it would be difficult and this will keep them from getting too loose over time (hopefully).

The free plastic pipette is incredibly useful for making perfumes and much preferable to the dropper tops most essential oils come with, in my opinion.
