I have done it: from Mexico into Phoenix Arizona, USA to London, Cape Town to Zimbabwe. I used a roll on deoderant stick which was almost finnished, unscrewed it all the way and inserted the packet(which was sealed in a packet of aftershave for odor controll) into the deo stick and replaced the plastic holder(which the deo sits on) screwed it in to a normal position and put in in my travel bag with toiletries and put that in my suitcase under the clothes. It is always stressful though and I prefer to get more where I am going.
