The secret of a good travel kit is to be clear about the needs of the destination and the means of transport. To travel by plane without checking in, or for short breaks, the mini sizes, the capsule format, which allows you to take only the essentials, the solid alternative to shampoos and perfumes and the transparent toiletry bags are the most practical. To optimize the space in the suitcase, opting for multi-use products and those that can be shared with the family is the best strategy.
