For your decanting needs: a 10ml refillable aluminum roll-on travel perfume bottle in silver. It also features a cut out in the aluminum so that you are able to see how much fragrance remains in the bottle. It is just a little taller than 4". Perfect for your purse or vacation! (Just a note that the glass bottle portion of this cannot be removed from the outer aluminum covering. You remove the roller ball to fill the bottle.) Also please note that although the photo does not show the rollerball portion of this, you will receive it!!
