The Sentinel — Superhero Octopus Mug
A watchful force from the electric deep.
The Sentinel features original SIRENROBYN artwork in ember red, electric blue, and weathered gold, set against a storm-lit underwater world. The complete illustration appears on one side, balanced by the SIRENROBYN wordmark on the reverse.
A black interior and matching handle extend the artwork’s dramatic color story beyond the canvas, creating a bold companion for coffee, tea, and beautifully unruly souls.
Original SIRENROBYN artwork designed in California. Available in 11 oz and 15 oz sizes. Ceramic mug is microwave and dishwasher safe.
