Go Ahead, Pick My Seat Heat-Activated, Design-Appearing Mug

SURPRISE!

Be part of a fun (& semi-secret) society of seat fillers. This retro-style design from OTL Seat Fillers is the perfect way to show your playful side. The quirky yellow design of "Go Ahead, Pick My Seat" will magically appear when your all-black mug is filled with hot liquid. It's sure to put a smile on your face, especially on those mornings when you really need a little something-something!

IMPORTANT! This mug is shipped directly to you by the manufacturer. It's a print-on-demand item that goes into production as soon as you purchase it and is subject to a no-refunds or exchange policy except (of course) for manufacturer defects. We anticipate it'll be perfect, though!
