all of the bottles are of poor quality and either tend to leak or straight up ooze liquids. the zippered case is made of a nice thick plastic that's pretty aesthetically pleasing. it would make a nice cosmetics case. however, it does not pair well with leaky bottles. the zipper is cloth, so it will not contain spills. honestly, the best product i've used for frequent travel is a quart size freezer ziplock with a sliding sipper. buy travel size shampoos or GoTubes then refill them when you're back a home again. those bottles work much better.
