Most airports would only allow a maximum of 100ml liquid to be brought inside the airplane for security reasons. Of course, you do not want to leave behind your expensive perfumes for not following the rules. That’s why it’s practical to transfer just the right amount that you need for your travel in smaller bottles. This travel perfume bottle is easily refillable. It has a sub-filling bottom that allows you to pump perfume from your original bottle and straight into this one!
