My wife and I have tons of different, old fragrance perfume bottles that we actually use around our home as flower vases. Not all fragrance perfume bottles are able to be used in this manner, however there are plenty of hers that we can use to house flowers after they are empty of the fragrance perfume that once filled them up. All we do is take a pair pliers and remove the metal cap on the top, which opens up the fragrance perfume bottles. Then after washing them out a few times, they are ready to be used as vases. You see, there are so many great looking fragrance perfume bottles that they make these days, that many can serve as great vases once you are done using up the product that they come with. So far there are about a dozen old fragrance perfume bottles that have been converted into flower vases in our house, and that number steadily grows by one more each time my wife finishes off a bottle of fragrance perfume that has the right shape and feel to become a newly converted flower vase!
