This mug is fun. The art shows up nicely when hot liquid hits it. Used it for my coffee every morning and enjoyed the surprise. Just wish shipping was faster, took a bit longer than expected.

This mug shows the bird design when hot coffee is poured in. It’s fun to watch! Quality feels nice, but it arrived later than I hoped. Overall a solid buy for something unique.

Fajny kubek. Zmiana koloru po nalaniu gorącej kawy jest ciekawa. Rysunek ptaka wygląda przyjemnie, ale chyba mógłby być większy. Czekanie na dostawę trwało trochę za długo.

The mug works as advertised. It changes colors with heat, which is cool. Slightly smaller than my usual mugs but still nice for coffee. Shipping took a while though.

This mug is cool. It changes colors with hot drinks, which surprised me. The art style is cute and minimal. However, the black finish isn’t as shiny as I’d hoped, a little dull even when clean.

这款杯子很有趣,热饮时能看到小鸟。拿在手里重量合适。唯一问题是颜色比我预期的深了点,但还不错。在家用喝咖啡挺好的。

Кружка выглядит прикольно. Узнала о ее рисунке только после горячего чая. Обидно, что она чуть меньше по размеру, чем ожидала.

The mug shows the bird design only when hot liquid is inside. It’s a fun touch for coffee lovers. Just be careful—it stains easily if you leave it dirty too long.
