1, perfume is very volatile, and its table is fatal to perfume bottles. The tight gap between bottle mouth and bottle cap is the intrinsic standard of perfume bottle.

It is a clear, transparent liquid with high clarity. The color of perfume will not change for a long time. However, perfume containing jasmine essential oil will be more and more darker. This is due to the volatilization of perfume in perfume.
3, taste is absolutely the most important in identifying the quality of perfume. High quality perfume is pure, without pungent alcohol flavor, and the fragrance can last for a period of time.

This is the degree of fragrance used in everyday perfumes. When you choose perfume, you can't smell the bottle directly, but use the test paper. But you can't smell it immediately after you spray it. Because the content of alcohol in perfume is as high as 80%. So you need to wait for the alcohol to volatilize before you can distinguish the good and bad of perfume. Generally, the waiting time is 5 minutes left and right.
