A train case is a cosmetic and toiletry travel partner for commuters to keep essential items accessible while aboard trains, planes, and automobiles. They often have mirrors inside, transforming a box for toiletries into a miniature vanity equipped with everything you need to prepare for bed or spruce up before your arrival. Some makeup train cases have shelves, drawers, and dividers to help organize your cosmetics, so you know where everything is whether you’re all-aboard or glamming up at home.
