Your Morning Coffee Just Got a Little Love Letter
Pour your coffee. Watch the hearts appear.
That plain black mug? It melts away the moment hot coffee hits it. Tiny red hearts bloom across the side. And the handle? Shaped like a heart you can hold.
It turns a normal morning into a small, sweet moment. The kind of thing that makes you smile before you've even had your first sip. Eris™ pairs a heat-activated heart reveal with a heart-shaped handle, so the magic happens every single time you pour.
Already a favorite morning ritual in 18,000+ homes
✓ HEARTS APPEAR LIKE MAGIC IN SECONDS
Pour any drink over 60°C and the black coating fades to white. Red hearts cascade down the side. Every pour feels like a tiny gift to yourself.
✓ A HANDLE SHAPED LIKE LOVE
The heart-shaped handle fits your fingers softly. It feels balanced, sturdy, and just a little romantic. A sweet detail you'll notice every morning.
✓ HOLDS 11 OZ OF YOUR FAVORITE DRINK
Big enough for a full coffee, hot cocoa, or tea. Made from glazed ceramic with a smooth finish that stays vibrant pour after pour.
✓ THE GIFT THAT MAKES PEOPLE SMILE
Wrap it for Valentine's Day, an anniversary, a birthday, or just because. The reveal moment makes it feel personal — every time they pour, they think of you.

Frequently asked questions
How hot does my drink need to be for the hearts to appear?
Around 60°C (140°F) or higher. Most coffee, tea, and hot cocoa will trigger the reveal within seconds.
Will the hearts fade over time?
The heat-reactive coating is built to last with regular use. To keep it looking its best, we recommend hand washing instead of the dishwasher.
Does the design come back when the drink cools?
Yes — once the mug cools down, the black coating returns and hides the hearts again. The reveal works every time you refill it.
Is it safe to put in the microwave?
Yes, the mug is microwave safe. Just be gentle with it — ceramic can be fragile.
How to use
Step 1: Rinse the mug with warm water before first use.
Step 2: Pour in any hot drink over 60°C.
Step 3: Watch the hearts cascade across the side in seconds.
Step 4: Hand wash gently to keep the reveal looking fresh for years.

Do these run true to size? They fit true to size for most. If you're between sizes or prefer a more relaxed fit, we suggest sizing up one.
Can I wear this to the office? Yes. Styled with the right pieces, it reads polished and professional while keeping the silhouette clean.
Will the fabric fade after washing? The fabric is pre-washed to soften the feel and minimize fading. Wash cold and hang dry to keep the color rich.
Wrong size? Displeased? No problem! If for any reason you are not satisfied with the product, we offer a 60 day return policy.
To minimize our carbon footprint, we don't keep all our products in stock. Instead, we make them on demand, which may result in slightly longer delivery times. This approach lets us offer better prices, benefits the environment, and helps avoid unnecessary waste. Once your payment is confirmed, we'll begin processing your order right away — it typically takes 1–3 business days to prepare and ship. After dispatch, you'll receive a confirmation email with a tracking number, and you can follow your order anytime on the Track Your Order page. On average, you'll receive your order within 3–8 working days after dispatch.
