My partner & I like to split our clothes between both suitcases (in case one gets lost in transit, at least we will both still have clothes at the other end!) and we also double up on toiletries, having one bagful in each suitcase with identical contents. To this end, the Reisenthel kids' toilet bags are absolutely ideal, big enough for all the travel sized bottles, cotton buds, pills, contact lenses etc but without swamping our cases. They are also super well made and come in lovely, fun patterns (we chose the Cactus Blue and the Green Wood)...who wants boring adult stuff anyway!! 😀
