I love these! The price is VERY good...all the flavors are really good! The peppermint one is my favorite and I would gladly take more of that before the others. Though the others aren't lacking at all, I'm just a peppermint fan! Will be buying more when my others get low! Thanks so much!

I love little white kernels of popped corn.  This was good stuff, but I think I'll try a larger white kernel to pop next time, my preference.

Got this as a gift for the office.  It's nice to get people to take a break from work to see what they get.  Unfortunately, its not well mixed.  It's almost gone and so far, all the black ones are not the licorice (and that is the good flavor compared to the other one, ick!), same goes to the white ones and the there was only one pair of the blue to be played :(
