The first item to day is a travel dispenser.

If you have taken an airplane anywhere in the last decade, you probably know that you are restricted from taking liquids bigger than 100 ml through security, and common sense will help you to not take large bottles with you anyway, so this dispenser is a perfect solution. It has 4 individual bottles for things like shampoo, conditioner, soap and lotion or hand sanitizer, which go into the single unit.

You then can label them accordingly, save that precious cargo space, and add a little extra safety to avoid accidental spills in your luggage so that your shirts don’t look like Monica Lewinski’s top in 1998.
