The adjustable band means it actually fits my 10-year-old without slipping, and watching it shift from blue to green while she did her homework was oddly fascinating. She’s worn it every day for a week straight, which says everything about how much she loves it.

My niece squealed when she tried it on and the color changed from purple to green right before our eyes, and she hasn't taken it off since. The size adjustment is actually really easy to do, even for her little fingers, and it feels light enough that she forgets she's wearing it during school.

The color shift is seriously addictive—I caught myself staring at it during class when the stone went from blue to purple mid-lecture. My daughter loves that it adjusts to fit her finger perfectly on any day, and it’s held up through hand-washing without fading.
