Sách tắm đổi màu – Câu chuyện Grinch đánh cắp Giáng sinh!

These are a huge hit at bath time — my little one loves watching the Grinch’s face appear out of nowhere when the pages get wet. The color change is genuinely instant and keeps her entertained through the whole bath.

I was skeptical about the "magic" color reveal, but my 2-year-old was absolutely mesmerized when the Grinch's face appeared on the pages in the bathwater. It’s durable, waterproof, and actually held up after a week of splashing around.

The color change really does work like magic in the water—my little one giggled each time the Grinch appeared on a new page. Pages are soft and easy for small hands to grab, plus it's held up well to daily splashing. I’d call bath time a win now.
