Not to pile on... the chinese are getting good at some of these.
Here's a comparison from the nice guys at TCC:
Counterfeiting is a serious deal and my only issue is that someone other than Titleist is benefiting from these fakes which just hurts the company. Tag was probably cut out of an OTR cover. Puckering and letters that don't line up are key indicators.
As TNT said, if it's too good to be true... it really is! RUN AWAY!
