I will be doing some traveling next week. I will only be going over the weekend, so I will not have any checked luggage, only carry-on. That being the case I read the traveling wiki on here. I plan on purchasing some blades once I reach my destination. The wiki suggests using a toilet paper or paper towel tube to package your brush. Should I shove something in the leftover space in the tube to cushion or fill out the roll? Tissue or something? What would be the best way to pack a razor? Is a DE or SE more travel-capable? Has anyone had difficulties/issues traveling with just a carry-on before? Would a toilet paper/paper towel tube look suspect going through the scanner?
