Why It Matters

Heat Reveals It

325ml ceramic, heat reactive coating. Design appears when hot liquid is added. Hand wash recommended for longevity. Not microwave safe.

Black Until Hot

Pour the water and the design turns up. The kids ask to watch it, every single morning, and you let them.

Hidden Print

Most printed mugs show one design. This one hides the Islands print until heat brings it out, which is what makes it a gift.

STYLE IT YOUR WAY

Use It Your Way

Morning coffee that comes with a show. Pour the kettle and watch the Samoan design appear as the mug heats up. Keep one at work to confuse and impress coworkers who use the communal mugs. Gift it for the person who thinks they've seen every type of mug because they haven't seen this one. Perfect for birthdays, Christmas, and housewarming gifts that actually get talked about. Display it matte black on a shelf and let visitors discover the hidden design themselves when they make tea.
