Travelling requires you to pack limited things with you or else, you'll exceed your baggage weight limit. It's a frustrating scenario to imagine when you're already in the airport and you have to add extra charge for a not-so-smart move.
So when you're travelling light, you'll have the dilemma of leaving some of the things you want to bring during your trip. An example of this is leaving your bottle of perfume because they're too bulky or you're worrying that it will break inside your bag. It's not a problem in my case. I use Travalo, a small perfume bottle that can refill up to 5ml of your favorite scents.
It's very small and lightweight. You can even slip it inside your hand-carry bag. Bring one or two perfume bottles with you, it doesn't matter because the bottle is handy.
Never Travalo without one. You can check their website here for more details.
