...use a pill box or contact lens case for your toiletries next time you travel? Both types of containers are meant to hold precious cargo and in the case of the contact lens case, liquid! The chambers are big enough to hold a few days supply of cleanser, toner, serum, cream, primer and foundation and most of the containers are air tight.
Bonus: If you have extra chambers in the pill box, stash your rings and stud earrings inside!
