Au カラーチェンジングカップ

These cups are my new party essential. My guests couldn't stop watching the purple and blue design shift the moment I poured the drink in, and the color change is so quick it feels like a magic trick. Best few quid I've spent on something for the table.

The purple-to-blue gradient pops the second your drink hits the cup, and it’s honestly the main conversation starter at every party I’ve brought them to. They hold up well after a few washes too, which I didn’t expect from a limited edition novelty.

The colour shift is so smooth it feels like a party trick every time I pour a drink. The purple and blue design looks even better in person, and the cup handled a full round of cocktails without any issues. Guests kept asking where I got them.
