If a Transformers toy existed for grown women, it would be Parallelle's Traveller series of toiletry bags. Keep It ContainedThe Traveller is the brainchild of Annie Fan, a career designer of private-label bags for other brands. In 2022, she set out to design her own bag: the ultimate travel cosmetics bag. Today, there are now four sizes of Traveller, all with the same sturdy, vegan leather and water-resistant cotton exterior. Even though I have tested more than 20 toiletry bags in the past year, I was still impressed.
