Most females use the large spray bottles of perfume instead of oil roll-on perfumes. Both have its benefits, but oil perfume is definitely not as popular as it should be considering its attributes. It is typically is more potent than a spray perfume so you use less. Also, it is great for travel as it comes in a small bottle. Best part, it is usually cheaper than regular perfume. Our favorite scent, especially with summer time in the near future, is the Hawaiian intoxicating Kai fragrance. Kai’s spray perfume is 1.7 ounces for $72, while their oil perfume is only $45 for 1/8 of an ounce which lasts forever!
