Have You Tried These Grapes?

A friend of mine posted these on her Facebook and said they are really good and of course her kids love them so I'm ready to find them and buy them! Cotton candy grapes. I'm sure they've been 'a thing' for a long time but of course yours truly is behind the times, so I've not had the chance to steal a grape or 2 from the grocery store to try them. 

Where can I find them? Have you bought them for your family and if so did you love them? Cotton candy grapes, I have to get my hands on them. lol
