You know of Larry's site maybe a travel strop or a poormans strop. They are inexpensive and the poorman's strop I have is small enough to roll up in a shallow butter tub or sour cream tub to protect it. Any hard soap would work in the same sized tub. or get a shaving stick or fashion a puck into a shaving stick. I face lather so I never use a lather bowl. Synthetic brushes dry fast, work well and the RazoRock plissoft can be had for $10. I have one and its a great brush. A large pill bottle from the Pharmacy would hold it safe. Just bring the brush you want to travel with and ask at the pharmacy desk about a pill bottle that it would fit in. I've gotten bottles like that before. When I was in Basic I used hand sanitizer and hand lotion as aftershave so if all else fails. . .All joking aside any softer plastic travel bottle should work well enough for aftershave. 3 oz last awhile and who says you only get to bring one? Pack a few and then if you do have a break then you haven't lost everything. If you get one with a spray top it lets you use it with less waste so you would need less. I don't have a case for my brush yet but my travel kit right now has a Schick B3 or a parker style shavette and blades, A stick of Arko, and a travel spray bottle of Pinaud's Citrus Musk. My travel brush is a WD 20mm synthetic but I haven't been traveling since I got it. I used to use neutrogena shave cream since its brushless and worked well for me.

I've thought of packing a real straight but I'm too afraid of it getting lost. The Parker style cost me less than $2 on eBay so its my go to travel razor. The B3 stays home most days but I got it to use as a travel razor.
