I also picked this up for traveling. It packs very well. I would second the advice about drying it out after traveling, but I don't think it's too sensitive. i leave it (uncapped) in my bag for the 3-4 days that I'm away, and rinse and let it dry after getting home, and I don't have any trouble. The bristles
are shorter than on the brush I use every day, but the silvertip bristles are softer than the other. Works great; very happy with it.
