No, you won't always be at two and a half hearts; these two shirts come as a pair, and have radar.
Wait for it ...
That's right. The closer you are to your sweetie, the more hearts you'll have. So you'd better stay next to them all day, or you're going to have to deal with that annoying beeping sound like in The Legend of Zelda. Actually, they don't ever go down that far. Two and a half is the lowest. Whew!
They run off AAA batteries, and the animated decal is removable so that you can wash them. Check out the YouTube video below, and buy a set for yourself and your geek love today!
