So can I hand sand this to fit in here for travel without ruining it? its my spare back up brush, Its just I will be away from home for a little over a week from LA, Germany,Japan. And at all time's I must look my best I do have a travel kit that I brought of a member on here but it does not have a travel brush and the next brush I will buy will be one of Fido's new ones (when he makes them) also should I take a tried and tested razor or just a pack down travel one? I will only be taken carry on as I can take 15kg B/Class this means no waiting baggage collection, so I will have to get blades as I land and then either chuck them before departing to next stop or post home unless anyone has any better ideas?
