Updated daily, we can swipe the baubleApp against my Windows Phone to receive instant messages from the Tooth Fairy herself (today's involved snowflakes), and while that's cute - the nice thing is that this necklace and charm are just fine without the tech, too.
Since receiving our baubleApp, the fairyHeart has been issued in a fancier package, consisting of a heart-shaped tin filled with sparkly sprinkles and a note from the Tooth Fairy. At $17.50, it's also a reasonably-priced gift considering that they're hand-crafted.
