Hello everybody

I have just bought purple oud and want to check if it is legit or not,
I have a leather oud to compare with and i see some differences,The biggest difference is the thickness of the glass at the bottom, my leather oud is thicker and has different shape, the purple oud is supposed to be 250ml to but if the glass is not as thick then it will be more on this? Strange, as you can see its a different CD logo on both
