Gentlemen:

I have drip stands for all my brushes at home. For the travel brush, this is what I do:

I have an Edwin Jagger best badger travel brush in its own travel tube. When finished with the shave, I gently squeeze the water out of the brush, gently shake it a few times and then lay it on its side on an elevated platform — a hotel coffee mug, glass or whatever I can find until the next morning.

On the day of my departure, I don't use the brush so that I don't have to packed it wet; rather, I have sample packets of quality shave cream — Cade, Truefitt & Hill, etc. — and use them. By then my brush is dry from having been used the day before. I return it to the travel tube and pack it in my dopp kit. The process works quite well for me.

Regards,
Obie
