I got this travel tube as a gift from my friends the day before we took off for our Cheingmai(northern part of Thailand) trip. It is not only show how thoughtful they are, selecting each pieces putting in the cool bamboo tube but also remind me of a fair well gift from Dave my architect friend in Seattle. The survival kits, with a bunch of fun little things to lift up my mood during my long flight back home. For this time Luke and Gug put all useful little things to keep us awake and survive though our long road trip(8 hr. drive). We got a chance to use most of them. Our favourite is the roller balm which keep Bo awake when he really need it. Thank you guys.
