Hey guys, I recently decided to pickup a small travel humidor for my trips to Vegas. I am usually gone 3-5 days so I figured this briefcase style humi would be great for protection and it holds just the right amount. I notice that it doesn't have any humidification system built into it so do you think I should add something to it or should my cigars be fine for a couiple of days?

Please make any recommendations!
