Thankfully I found a solution. I bought this vanity bag from Muji a couple of days before I fly. It's pretty cool coz I can pack all my necessities into it, and coz it's see-through then there's no hassle to take it out and put into another plastic bag. I love the simplicity of the bag, clear plastic with grey trimmings. And it's cheap too. They come in variety of sizes; the one that I got is a medium.
Oh, what am I bringing with me? Some moisturizers to moisturize the skin since the air-conditioning (or any cold condition) really harsh mine. And an eye roll-on - a quick solution to prevent eye bags - anybody should get their eyes more puppy than puffy, right? If you're contact lense user like me, the contacts eye drops is pretty handy if you don't wanna remove that lenses (which I'm always lazy to do!). And not to forget - the lipgloss, especially for those who always prone to cracked lips. (yikes!).
Come on guys... there's no harm in wearing products! =)
