Once upon a time, there were two women who understood and set out to solve the plight of the modern-day traveler: having to toss anything over three ounces upon security screening at the airport. (Seriously, can we get no sympathy for that luxe moisturizer we saw tossed in the garbage?) Thus, they formed 3Floz , a service that would allow travelers to shop TSA-friendly minis of their favorite beauty products. Travelers could have these products shipped directly to their destination hotel and avoid the separation anxiety one would undoubtedly face when leaving a favorite, and necessary, beauty goody behind.
