I Have good working on city to city travelling so, I like this bag.
I have a leather messenger bag that I like.  It is made by Tuscany and it is called the Ancona.
I want to like leather bag and traveling length bag used.
Can you describe what you mean by a travel length bag?  Would it be ok to take on a flight, case dimensions vary, but it must fit under the seat infront?
I want to like dimensions vary must travel length bag.
Most airlines will limit carry on bags to 22 by 14 by 9.  That defines a carry on bag.
My family friends used on carry on bag.
I once bought a used leather bag.  It was filthy.  I cleaned the handles with a soft tooth brush.  Once it was dry I used leather conditioner. It was a really good bag.  I miss it.   
I want to like more than products used. soft tooth brush used my daugter.
I am considering making my own leather conditioner. I will use beeswax, cocoa butter and almond oil. On the stove I will melt the ingredients together. Once cool I will work the stuff into the leather, the when dy buff the bag to make it shine.
