I keep a stash of these around for emergency gifts. No one I have given this to as a gift has been disappointed, in fact they've all been delighted. Make sure to buy the accompanying funnel, though, since the opening is a little on the small side. I wish that Birchbox kept more in stock (i.e., with different inscriptions to choose from), so that I could give a bigger variety away. The size is good --- the 3.0z flask is nice for frequent fliers but this one's a good choice for burly he-men or for people who'll just be slipping it into their bag rather than travelling with it.
