From McBiff:

"The Cocksmith 14 OZ Executive Double Old Fashioned Black Velvet Glass.

Flat black GLASS 'Support your local Cocksmith' glassware. There is also a pufferfish printed on the bottom of each glass!!

The term Cocksmith was coined by Mcbiff and refers to a fantastic craft bartender. This is what McBiff calls the craft of making cocktails, and he fully supports a good Cocksmith."
