So it has been a few weeks since shaving with my DE and slowly with my straight. It is awesome! No more ripping at my face, no more ingrown hairs etc. that being said I travel a ton for work. Today I had a flight a brought my Gillete Black Beauty with my. I took the blade out put in my liquids bag....got searched. All of which is not a big deal. What retailers can I buy single DE blades? I travel for 2-4 days at a time nd don't need packs of blades. Any help here would be greatly appreciated.
