I saw these in Walmart today. They are made by Nestle and are the newest addition of their "Carb Select" line, which already includes Crunch bars.
I when impressed with the size of the bar. It isnt has huge as the normal Baby Ruth but definetly bigger than some other wimpy lc candy bars of seen, which are more like miniture versions. The candy bar is 140 cals and 3.5 carbs, sweetned with malitiol i think. I had to try one, and I have to say it was pretty darn good. I only ate half of it though because it was so big, and too avoid too many SAs all at once.
