title_body: Fake Glencairn Glass?
upvoted_answer: If you are asking if the glass was made by Glencairn Crystal, then the answer is: no, not likely.
  For one, the URL on the top of the box in your photo is different than the one that you will see if you follow the link above. For two, Glencairn Crystal is in Scotland - since the UK is no longer part of the EU (as the bottom of your box displays where your glass was manufactured,) it probably does not come from there. Then, there is the business with the trademark...
  Patents expire, and while this may not be manufactured by &quot;ye ol' Glencairn glass works incorporated,&quot; the glass is legitimate even if it does not contain the trademark etching of the company.
  As long as it has the actual shape as the glass on the box, then it is the real thing.
  What makes a glass a Glencairn is the design, in this instance:
  
  So, the design has become the thing.
  For instance, if I made a plastic flying disc, one could argue that it isn't a frisbee because it doesn't have the right trademark and wasn't made by an authorized party. But, as soon as we ask an objective third party 'what is this flying plastic disc thing that I am holding?' They would say, 'duh, it's a frisbee.'
  Just as if you ask someone (who knows what they are looking at,) 'what kind of whiskey glass is this?' They will say, 'it's a Glencairn.'
  So, does the glass have the authentic trademark? Probably not. Is it a Glencairn glass? Yes, it definitely is.
