Tips: In summer, the color change depends on the ice water, the lower the temperature, the brighter the color. In winter, when it is cold below 15°Or you put the cups directly in the refrigerator, the bright cup (original color) will automatically change to a bright color.If you add hot water to the cup at this time, the cup will change to its original color. Press the lid down on the top of the cup with a little force until you hear a "click" and then twist the lid a little, splash-proof lids reduce spillage.
