Au 變色杯

The color shift is so fun to watch—the purple melts into blue right as you pour, which made everyone at the BBQ stop and ask about it. They held up fine with ice and repeated refills, and the design stayed crisp the whole afternoon.

The purple-to-blue gradient looks even better in person, and watching the color shift as soon as I poured my drink in was a fun party trick. They held up fine through a full evening on the patio, no cracks or fading.

Filled mine with a sparkling water just to test it, and the color shift from purple to blue happened almost instantly as I swirled it. It’s become the go-to cup for every backyard hangout since, and the design really pops in the sun.
