We can thank our fellow Americans for a lot of great inventions. Honestly, we have a pretty innovative country on our hands! But occasionally, a good idea does jump across the pond, take root, and take off with American customers. This was exactly what happened with Rock Candy Crystals. Originally used as a sore throat remedy in Europe, these babies will have you taking a minute to appreciate the many great minds we have in the world. Since the late 1800's, Rock Candy Crystals have been a popular sweet treat for generations of Americans. One of the oldest candies we have, they're sure to bring a smile to anyone who takes a lick. Their 2.5 ounces of pure sugar may have you bouncing off the walls, but it's worth it, right? Of course, right! So what are you waiting for? Get your hands on one of the first candies to become retro, and thus, totally in style.
