My perfume only comes in a pour bottle which isn't how I like to wear my perfume because it is too strong in one location. This gives me a nice spray in the air that I can walk through so it's not so strong. It holds 20ml and is in a nice strong metal case to protect the inner glass section that holds the perfume. It comes with a funnel to pour with no mess or spills. When filling the bottle remove the inner glass bottle out of the metal casing by turning it counterclockwise and pulling it out. Then twist off the cap and fill using the funnel. Then just screw the cap back on and slide the glass bottle back inside the metal container. This comes in many colors. It fits nicely into my purse so I can take it with me. This is great to have when traveling and I want to take my perfume but not a huge large bottle that may leak in my suitcase.
