Hard too answer, without knowing which country you are in, but here is what we are talking about: http://www.spiegelau.com/craft-beer/craft-beer-glasses/ipa/
You tend to find them in department store/kitchen shops/anywhere you would find good glasses.
I'll have to keep a lookout. I live in the US, so it looks like I should be able to find and pick up some. Gives me a great gift idea for my mother-in-law who loves IPA's.
