Unlock the magic of color change with this Dolphin key chain. It’ll liven up any set of keys, transforming from translucent to purple in sunlight. Not only will it personalise your set of keys, but the Dolphin 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.
It's magic! Seriously, it's the magic of Del Sol's proprietary Spectrachrome® Technology. Spectrachrome crystals reveal their hidden colors when exposed to sunlight. NASA invented it for their space program, and Del Sol enhanced it for everyone under the sun! It's not rocket science, but then again, maybe it is.
