As a mother of two little ones under the age of two and someone that has travelled through too many international airports to count, travelling with liquids is probably a must considering how many accidents and unexpected situations can arise. Unfortunate as it is (despite it being for our own safety) regulations amongst several international airports have varying sizes of items and liquid items you can carry. Luckily with this travel pack the sizes are small enough to meet the guidelines, but are also large enough to hold what you might need. This set includes 4 clear bottles and a resealable clear bag making it easier for identification .
