My wife got tird of my ratty zip lock for my travel liquids.  I bought this and she was/is impressed.  Not overly impressed - its just a clear, zippered bag, but at least she is not as ashamed to travel with me.  We can both use the same security line now.  :)

It's sturdy, but not too stiff.  Can't think of anything I would change on this plastic, zippered pouch.
