Unlock the magic of color change with this metal wolf key chain. It’ll liven up any set of keys or backpack and makes for a great zipper pull, transforming from silver to blue with sunlight. Not only does it add personalization, but this color-changing key chain also makes for a perfect gift, promising to show off its brilliant color of fun every time it’s in the sun.
Much like a flower that blooms when exposed to sunlight, Del Sol's products change colors in the sun using their proprietary Spectrachrome® technology.
Spectrachrome® molecules in the products shift to colors visible to the human eye when exposed to UV sunlight.
Del Sol's Spectrachrome® formula for color change was developed from a concept originally researched by NASA for use in space.
