Either a CigarCaddy or an Otterbox. Both of these have an airtight seal. If the sticks are properly humidified you can safely leave them in for a couple of weeks without any humidification device. They have foam in them with "slots" for the cigars to safely travel without moving around. You can get them in many sizes from a 2 count to a 40 count. IMHO these are the best traveldors available.
