This is a ceramic mug shaped like a rum bottle with real cork at top. However, it has a cut-out for ice/liquid/straw on back. Marked with a paw and crossbones logo on the front and the Stray Pirate name and logo on the back, much like their matching Paw & Crossbones tumblers. On the bottom it says "Squid Felt+Fat Handmade in Philadelphia".

These are glazed in a bluish-green mottled zombie-like glaze.
