Avoid getting slimed with these tips for packing toiletries.

Buy inexpensive, reusable, travel-size containers and fill them with your own products. Never fill containers to the top, though: changes in air-pressure during a flight could cause the contents to expand and leak. To play it extra safe, put toiletry bottles in a resealable plastic bag within your kit. And put the kit itself in a plastic bag. If, after all this, you still end up with sunscreen on your Bruno Maglis, the travel gods simply have it in for you.
