I have really no idea, i know somewhere Mara had said that 10 drops could be added to 10ML bottle, so i would of thought in a full bottle of 5 ML you could add the 5 drops.
what is your Bombshell perfume anyway, is it off the website, or something you put together?
i know in my 5ML perfume bottles i will be adding 5 drops, but i also need to find something to fill up the 5ML as well lol!
